How do you Solve: -2x-7=-29

x=11

Step-by-step explanation: add 7 to both sides of the equal sign. the 7's get canceled out. -29 plus 7 is -22, bring down the -2x, so now you have -2x=-22, then you divide -2 on both sides (the -2x's get cancelled out)  and you get 11

hope I explained it good enough :)

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9
