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
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
65 = 2x - 7x 65 = -5x 65/-5 = -5x/-5 -13 = x
you need to reorder the problem by manipulating the numbers -2x-7=-x+13 group your variables and constants thus -x-2x=7+13 simplify -3x=20 simplify again x=-20/3

2x + 1 = 13; 2x = 12; x = 6
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.
3x+5 = 2x+13 3x-2x = 13-5 x = 8
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
If 9-2x =35 -2x = 35-9 -2x = 26 -x = 13 x = -13
13(2x - 1)
x-29 = 13+2x x-2x = 13+29 -x = 42 x = -42
