Question

Please give me the correct answer.​

Answer 1

You should divide both sides with 6

Answer 2

(multiply 2x - 1 by 6) But see below.

Explanation:

There are two things you could do first.

1. You could remove the brackets which is the same thing as the upper left. But you have to be careful.

6(2x - 1) = 12x - 6 Both terms have to be multiplied by 6

or

You could divide both sides by 6 and that too is a bit tricky.

18x / 6 + 30 / 6 = 3x + 5 = 2x - 1

I have found that the safer thing to do is the first answer (multiply 2x - 1 by 6)
