2(4x + 4) = (4x - 12)
8x + 8 = 4x - 12
8x - 4x + 8 = 4x - 4x - 12
4x + 8 = -12
4x + 8 - 8 = -12 - 8
4x = -20
4x/4 = -20/4
x = -5

Solve by the substitution method 4x-5y equals -8 4x plus 40 equals y?
4x-5y = -8 4x+40 = y => y = 4x+40 Substitute the value of y into the top equation: 4x-5(4x+40) = -8 4x-20x-200 = -8 4x-20x = 200-8 -16x = 192 Divide both sides by -16 to find the value of x: x = -12 Substitute the value of x into the original equations to find the value of y: Therefore: x = -12 and y = -8
