Question

Can someone help me on this pls i will give brainliest

Answer 1

His error is in step 3. The variable x is being multiplied by -7 and therefore he should have divided both sides by -7, not 7 as he did.

Answer 2

-7x + 25= 48
-7x + 25 = 48 - 25
-7x = 23
-7x/-7 = 23/-7
your answer is Step 3: he should have divided both sides by -7
