You have to get rid of 1/2 by multiplying it by its recriprocal which is like this: 1) 1/2 x 2/1 which equals to zero and you do the same to the other side. 2) -12 x 2/1 = -24x then multiply-24x with 7 which equals -168. 16-x= -24x -168 3) subtract 16 to the other side and subtract 24x with x 23x= -184 4) divide by 23 to isolate x and you get -8 5) x=-8
First you need to multiply 1/2 by 16, then multiply 1/2 by x to get 8-1/2x=-12(x+7). Then you multiply-12 by x to get-12x an then you multiply-12 by 7 so your equation looks like this 8-1/2x=-12x+-84. Combine the like terms and divide by the number with the x and you have your answer
if she did that she would have walked 36 miles multipy all of the numbers and theres ur answer i think i am so tired so if its wrong i am sooo sorry i havent slept in two days.... hope u have a better day than mine
