This is much easier to explain with a picture so...
First, simplify the coefficients. Then, simplify the variables. The y's cancel each other out so, you have your answer of -3x

531 = ( X × 6) + 21<br><br> LAST QUESTIONNNN

Monica [59]

To solve for X: First you multiply x and 6 then subtract 21 on both sides and then divide by 6

531 = ( X × 6) + 21
531 = 6X + 21
510 = 6X
85 = X

Hope this helps :)
