Question

3x - x + 2 = 12.

Answer 1

first subtract 2 from both sides

Answer 2

then combine your like terms which are 3x-3

Answer 3

@mitu12 how did you get -3??? just curious
it should be subtract 2 from both sides which ends up as 3x-x=10 because the two cancels itself out
then add like terms so now it is 2x=10
then divide 2x/2=10/2 x=5
