    Answer:

    So let’s break this question down…

    x+1=2x-2=5x+7

    We move all terms to the left:

    3x+1-(2x-2)=0

    We get rid of parentheses

    3x-2x+2+1=0

    We add all the numbers together, and all the variables

    x+3=0

    We move all terms containing x to the left, all other terms to the right

    x=-3
