Best ResponseYou've already chosen the best response.0since the x is multiplied by a number, you do the operation (+, _, *, /) that "undoes" multiplication, which is division, so that x ends up alone on that side of the = sign.

Best ResponseYou've already chosen the best response.0the multiplicative identity is 1. if you have a number x, you multiply it by its reciprocal to get 1. so if you multiply 8 by 1/8, you will get 1. since you are multiplying by 1/8 on one side of the equation, you must do it on the other side of the equation as well so you have 8x times 1/8 = 40 times 1/8
