Jorge solves the equation 4x - (x + 20) + 6 = 2(3x + 8) using the steps below.
step 1: 4x - x + 2 + 6 = 6x + 16
step 2: 3x + 8 = 6x + 16
step 3: 8 - 16 = 6x - 3x
step 4: -8 = 3x
step 5: -8/3 = x
jorge verifies his solution by substituting -8/3 into the original equation for x. he determines that his solution is incorrect. which best describes jorge’s error?
a. jorge distributed incorrectly.
b. jorge incorrectly combined like terms.
c. jorge incorrectly applied the addition and subtraction properties of equality.
d. jorge incorrectly applied the multiplication and division properties of equality.
