in your first equation the coefficient of y is 1, so that becomes your obvious choice.
y = 5x - 3
sub that into the 2nd
3x - 8(5x-3) = 24
3x - 40x + 24 = 24
-37x = 0
x = 0
back into y = 5x-3
y = 0 - 3 = -3
x = 0 , y = -3
Solve the system by substitution.
-5x + y = -3
3x - 8y = 24
I'm not sure which equation to choose as I begin to find the y value. Some assistance would be greatly appreciated! Thank you!
