Answer:

B. Incorrect with error in STEP 1

Explanation:

3x - x + 4 = 4(2x - 1)

Step 1: Simplify

2x + 4 = 8x - 4

Step 2: Subtract 8x from both sides.

2x+4−8x=8x−4−8x

−6x+4=−4

Step 3: Subtract 4 from both sides.

−6x+4−4=−4−4

−6x=−8

Step 4: Divide both sides by -6.

-6x/-6 = -8/-6

x = 4/3

so, the other answer is wrong because she did not multiply the numbers in the parenthesis correctly
