    No solution First, change the first equation 4(7x - 6y)= 4(-88.5) 28x - 24y = -354 Then, you add or subtract the two equations to eliminate one variable and solve for the other. However... 28x - 24y = -354 -28x + 24y = -354 ------------------ If you add the equations, both variables are eliminated, and if you subtract them, neither equation is eliminated. So, NO SOLUTION
