Step-by-step explanation:
-2y-3y+8=8-5y-12
-2-3y=-5y
-5y+8=8-5y-12
inverse operation: add 5y to both side
-5y+8=8-5y-12
+5y +5y
-5y+5y=0, so it cancels out both -5ys
8=8-12
8=-4

What is Linear Equations in Two Variables?Linear equations are equations which are in the form of ax + by + c = 0, where a, b, and c are real numbers and also coefficients of both the variables, x and y, must not be equal to zero.
There are infinitely many solutions for a linear equation in two variables.
System of linear equations in two variables consist of two or more equations which are linear in two variables.
System of equations given here are,
3y = 18x + 6 and y = 2x + 14
We are solving this by substitution method.
Substituting y = 2x + 14 in 3y = 18x + 6, we have,
3 (2x + 14) = 18x + 6
Applying distributive property on the left hand side of the equation,
(3 × 2x) + (3 × 14) = 18x + 6
6x + 42 = 18x + 6
42 - 6 = 18x - 6x
36 = 12x
x = 3
Substituting x = 3 in y = 2x + 14,
y = (2 × 3) + 14
y = 20
Hence, the value of y in the solution to the system of linear equations 3y=18x+6 and y=2x+14 is 20.

use multiplcation to solve the proportion. a/40 = 3/10
Answer:
a=12
Step-by-step explanation:
a/40=3/10
10 x 4=40, so
3 x 4=12
a=12
Answer:
[tex]\boxed{\sf{x=12}}[/tex]
Step-by-step explanation:
Isolate the term of a from one side of the equation.
Solution: Multiplication property of equation.
a/40=3/10
First, multiply by 10 from both sides.
[tex]\sf{\dfrac{a}{40}\cdot \:10=\dfrac{3}{10}\cdot \:10}[/tex]
Solve.
a/4=3
Then, multiply by 4 from both sides.
4a/4=3*4
Solve.
3*4=12
a=12
As a result, the correct answer is a=12.

Answer:
[tex] \boxed{ \ - \frac{3}{45} }[/tex]
Step-by-step explanation:
10 3/9 - 10 2/5
we need to convert mixed fractions to improper fractions
[tex]10 \frac{3}{9} = \frac{10 \times 9 + 3}{9} = \frac{93}{9} [/tex]
[tex]10 \frac{2}{5} = \frac{10 \times 5 + 2}{5} = \frac{52}{5} [/tex]
Now, we have 93/9 - 52/5
We need to equate the denominators, before subtracting them.
[tex] \frac{93}{9} - \frac{52}{5} = \frac{93 \times 5}{45} - \frac{52 \times 9}{45} [/tex]
[tex] \frac{465}{45} - \frac{468}{45} [/tex]
[tex] \frac{ - 3}{45} [/tex]
[tex] \boxed{ - \frac{3}{45} }[/tex]
The result of 10 3/9- 10 2/5 is - 3/45

True or False?
a. If x is a nontrivial solution of Ax = 0, then every entry in x is nonzero.
b. The equation x= x2u + x3v, with x2 and x3 free (and neither u nor v a multiple of the other), describes a plane through the origin.
c. The equation Ax = b is homogeneous if the zero vector is a solution.
d. The effect of adding p to a vector is to move the vector in a direction parallel to p.
In a situation where x is a nontrivial solution, then every entry in x should not be nonzero. Therefore, it's false.
What is a nontrivial solution?A nontrivial solution simply means a system of equation where the determinant of the coefficient is zero. When x is a nontrivial solution of Ax = 0, then at least one entry should be nonzero.
The equation x= x2u + x3v, with x2 and x3 free (and neither u nor v a multiple of the other), describes a plane through the origin. This is true. Since they're free variables, the space span has dimensions and this spans through the origin.
The equation Ax = b is homogeneous if the zero vector is a solution. Since x = 0 is a solution. Therefore, Ax = b. Hence, b = 0.
The effect of adding p to a vector is to move the vector in a direction parallel to p. It should be noted that adding p to a vector moves it in a direction that's parallel.
