This question is asking to find the answer of the variable x, and to do that, you need to isolate the variable, aka get it alone.
10x+2=32 (you must get rid of the 2 first, so do the opposite sign, so if positive, subtract the 2 from both sides.)
10x=30 (Divide 10 from x to get the answer.)
x=3!
Hope this helped you!
