Best ResponseYou've already chosen the best response.2If you have an equation of the form a(bx + c) = d Then i). divide both sides by a ii). add the opposite of c to both sides iii). divide both sides by b OR i). multiply a by (bx + c) by the distributive property to obtain (ab)x + ac = d ii). add the opposite of ac to both sides iii). divide both sides by ab Note: @izziewoods and @winterfez we don't give out answers or do an entire solution except for the final step, because that does not help the person wanting help to learn. So either teach, otherwise you may be reported. I suggest you erase your answers.

Best ResponseYou've already chosen the best response.0the main goal is to get x alone, of course, so when you see parenthesis, automatically look at if you can get rid of the stuff outside the parenthesis first. once you done that get the term containing x isolated at one side of the equal sign. if then the x is still not alone, divide to isolate.
