Answer:
{x,y}={-8,-2}
Step-by-step explanation:
[1] x = 2y - 4
Plug this in for variable x in equation [2]
[2] 7•(2y-4) + 5y = -66
[2] 19y = -38
Solve equation [2] for the variable y
[2] 19y = - 38
[2] y = - 2
By now we know this much :
x = 2y-4
y = -2
Use the y value to solve for x
x = 2(-2)-4 = -8
