Answer:

(2,3)

Step-by-step explanation:

- Substitute the equation for y instead of the y variable.

-3x - 2(5x - 7) = -12

-3x - 10x + 14 = -12

-13x = -26

x = 2

- Now substitute the value of x into the other equation.

y = 5x - 7

y = 5(2) - 7

y = 10 - 7

y = 3

Answer:

x = 2 and y = 3

Step-by-step explanation:

y = 5x - 7

-3x - 2y = -12

Substitute y into the second equation:

-3x - 2(5x-7) = -12

Simplify:

-13x = -26

x = 2

Substitute x into the first equation:

y = 5(2) - 7

y = 10 - 7

y = 3
