Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
Rearrange the second equation as y = -3x+7
Substitute into the first equation
8x - (-3x+7) = 19
Distribute the negative
9x + 3x - 7 = 19
12x - 7 = 19
12x = 19 + 7
12x = 26
x =
y =
...
...
Rearrange the first equation as y = 4x + 11
Substitute into the second equation
6(4x+11) + 4x = -3
Distribute the 6
24x + 66 + 4x = -3
combine like terms
28x + 66 = -3
28x = -3 - 66
28x = -69
y =
