You have the following expression:
4x = 2 - 4(2 - 3x)
step1:
4x = 2 - 8 + 12x Distributive property (the factor of the second term right side has been expanded)
step2:
4x = -6 + 12x Combine like terms (the operation 2 - 8 us equal to -6)
step3:
-8x = -6 Subtraction property of equality (you subtract 12x both sides)
step4:
x = 3/4 Division property of equality (you divide by -8 both sides and simpliy)
