Solve by the substitution method
6x + 2y =-46
-7x+ y = 57
:
Use the 2nd equation for substitution in the 1st equation
-7x + y = 57
y = 7x + 57
:
Replace y with (7x+57) in the 1st equation
6x + 2(7x+57) = -46
6x + 14x + 114 = -46
6x + 14x = -46 - 114
20x = -160
x = %28-160%29%2F20
x = -8
:
Find y, substitute -8 for x in: y = 7x + 57
y = 7(-8) + 57
y = -56 + 57
y = 1
:
Check solutions in the 1st equation: 6x + 2y =-46
6(-8) + 2(1) =
-48 + 2 = -46, confirms our solutions of x=-8, y=1
