What is the solution to this system of equation?

x=2y-4

7x+5y = - 66

x=-8 y=-2

Step-by-step explanation:

substitute x for 2y-4

7 (2y-4) + 5y=-66

factor

14y-28+5y=-66

add 28 on both sides

14y+5y=-38

19y=-38

divide by 19 on both sides

y = - (38/19)

y=-2

Plug - 2 into the first equation for y

x=2 (-2) - 4

x=-4-4

x=-8
