Step-by-step explanation:
elimination of x:
-6x +5y = 1
6x + 4y = -10
___________+
9y = -9
y = -9/9 = -1
elimination of y:
-24x +20y = 4
30x + 20y = -50
_____________-
-54x = 54
x = 54/-54 = -1
{ -1, -1}
[tex]\huge{ \mathcal{ \underline{ Answer }\: \: ✓ }}[/tex]
The given equations are :
[tex]\longrightarrow - 6x + 5y = 1[/tex]
[tex]\longrightarrow6x + 4y = - 10[/tex]
let's add the equations
[tex] \longrightarrow\small{ - 6x + 5y +6x + 4y = 1 + ( - 10)}[/tex]
[tex]\longrightarrow9y = - 9[/tex]
[tex]\longrightarrow y = - 1[/tex]
now, let's plug the value of y in first equation :
[tex]\longrightarrow - 6x + (5 \times - 1) = 1[/tex]
[tex]\longrightarrow - 6x - 5 = 1[/tex]
[tex]\longrightarrow - 6x = 6[/tex]
[tex]\longrightarrow x = - 1[/tex]

how to solve multi-step equations
Answer:
1. Use the Distributive Property of Multiplication over Addition to remove any grouping symbols such as square brackets, parentheses, and so on.
2. If feasible, combine like terms to simplify both sides of the problem.
3. Determine where you want to store the variable, since this will assist you decide where to put the constant.
4. Remove numbers or variables by using inverse operations: addition and subtraction are inverse operations, as are multiplication and division.

What is 34.69$ + 9% (will give brainliest) (explain how you got your answer)
Answer: $34.78
Step-by-step explanation:
Answer:
$37.81
Step-by-step explanation:
I set up a true proportion equation.
x/$34.69 = 9/100
If you cross multiply, you'll find the value of x, which is 9%.
34.69 x 9 ÷ 100 = 3.12
$3.12 is 9% of 34.69; add them together to get the total.
$34.69 + $3.12 = $37.81

HELP MEEEEE!!!!!!!!!!!
that is not 43 it is a division sign
Hi there!
»»————- ★ ————-««
I believe your answer is:
[tex]m=\frac{2}{3}[/tex]
»»————- ★ ————-««
Here’s why:
We are given the equation of: [tex]m+\frac{4}{3}=2[/tex].I have noted that the (4/3) is a fraction and not a '43'. We would use inverse operations to solve for m.⸻⸻⸻⸻
[tex]\boxed{\text{Solving for 'm':}}\\\\m +\frac{4}{3} =2\\----------\\\rightarrow m + \frac{4}{3}-\frac{4}{3}=2-\frac{4}{3}\\\\\rightarrow\boxed{m=\frac{2}{3}}\\----------\\\boxed{{2-\frac{4}{3}}}\\\\\rightarrow \frac{2}{1}=\frac{2*3}{1*3}=\boxed{\frac{6}{3}}\\\\\rightarrow\frac{6}{3}-\frac{4}{3}=\boxed{\frac{2}{3}}[/tex]
