Solve the system of equations using the substitution method. {y=−3x+7x=−2y−16 Enter your answers in the boxes. x= y=

Answer 1

Here is the break down of the answer x=6 and y=-11

Explanation:

Answer 2

The solution would be (6, -11)

Explanation:

In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.

x = -2y - 16

x = -2(-3x + 7) - 16

x = 6x - 14 - 16

x = 6x - 30

-5x = -30

x = 6

Now that we have the value of x, we can find the value of y.

y = -3x + 7

y = -3(6) + 7

y = -18 + 7

y = -11
