HELP THIS IS DUE SOON!

find the error!

Answer 1

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

Answer 2

Step 1

Explanation:

they were supposed to multiply 2x by 4 and -1 by 4 but they only multiplied 2x by 4.
