solve either equation for x or y and substitute it into the other equation:
-6x+y = 50
y = 6x+50
so,
7x+9(6x+50) = -38
7x + 54x + 450 = -38
61x = -488
x = -8
now, use that value in either equation to get y:
y = 6(-8) + 50 = 2
-6x+y = 50
y = 6x+50
so,
7x+9(6x+50) = -38
7x + 54x + 450 = -38
61x = -488
x = -8
now, use that value in either equation to get y:
y = 6(-8) + 50 = 2
