5y - 4x = -7
2y + 4x = 14
Solve the system of equation

Answers

Answer 1

Answer:

( 4 , 1 )

Step-by-step explanation:

when canceling out the y values and then adding the two functions together you get

7y = 7

dividing by seven you get y = 1

when plugging y = 1 into the first quation you get

5 - 4x = -7

subtract 5 from both sides

-4x = -12

divide both sides by negetive four

x = 3

then with plugging in y = 1 for the second equation you get

2 + 4x = 14

subtract 2 from both sides

4x = 12

divide both sides by 4

x = 3

you then check your answers and get the point of (4, 1) for your answer.

Mary, Peter, and Lucy were picking chestnuts. Mary picked twice as much chestnuts than Peter. Lucy picked 2 kg more than Peter. Together the three of them picked 26 kg of chestnuts. How many kilograms did each of them pick?

Answers

Answer and Step-by-step explanation: Let \displaystyle xx be the amount Peter picked. Then Mary and Lucy picked \displaystyle 2x2x and \displaystyle x+2x+2, respectively. So

\displaystyle x+2x+x+2=26x+2x+x+2=26

\displaystyle 4x=244x=24

\displaystyle x=6x=6

Therefore, Peter, Mary, and Lucy picked 6, 12, and 8 kg, respectively.

Peter picked 6 kilograms of chestnuts.

Mary picked 12 kilograms of chestnuts.

Lucy picked 8 kilograms of chestnuts.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Let Peter pick x kilograms of chestnuts.

Given that Mary picked twice as many chestnuts as Peter

So, Mary picks 2x kilograms of chestnuts.

And Lucy picks  x + 2 kilograms of chestnuts

Together the three of them picked 26 kg of chestnuts

So, x + 2x + x + 2 = 26

4x + 2= 26

4x= 26-2

4x= 24

4x/4= 24/4

x= 6

Thus, Peter picked 6 kilograms of chestnuts.

⇒ 2x

⇒ 2 (6)

⇒ 12

Thus, Mary picked 12 kilograms of chestnuts.

⇒ x + 2

⇒ 6 + 2

⇒ 8

Thus, Lucy picked 8 kilograms of chestnuts.
