What is the solution of the system of equations?

y = –3x + 7
y = 2x – 8

(3,-2)

Step-by-step explanation:

-3x + 7 = 2x - 8

-3x - 2x = -8 - 7

-5x = -15

x = -15/-5

x = 3  

y = 2x - 8

y = 2(3) - 8

y = 6 - 8

y = -2  

solution is (3,-2)

(3,-2)

Step-by-step explanation:

The easiest way to solve this is to realize that in both equations, the ys must have the same value. So the right side of each equation can be equal.

-3x + 7 = 2x - 8            Add 8 to both sides

-3x + 7 + 8 = 2x           Combine

-3x + 15 = 2x                Add 3x to both sides

15 = 2x + 3x                 Combine and exchange sides

5x = 15                         Divide by 5

x = 15/5          

x = 3

Use y = 2x - 8 to solve for y

y = 2(3)  = 8

y = 6 - 8

y = - 2
