Depending on how the problem is written. 2x + 3 - 5x + 10 -3x + 13 ■ Or... 2x + 3 - (5x + 10) -3x - 7 ■ I think you want the second answer.
If 2x - 13 = 5 then 2x = 5 + 13 (we have in effect added 13 to both sides of the equation in this step) 2x = 18 x = 9.
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
-2x+5=13 you subtract 5 away from +5 and this cancels out. you then do the same to the other side by taking 5 away from 13 therefor you get 8. Now you have -2x=8, take -2x and divide it into 8 and you get 4.
Here is the answer with Steps: 15x - 18 = -2x - 5 15x = -2x + 13 17x = 13 x = 13/17 x ~ .764705882
