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
