Question

14-(x+5)=3(x+9)-10 please help quick and show work!

Answer 1

x=-2

Explanation:

14-(x+5)=3(x+9)-10

14-x-5=3x+(3 * 9)-10

14-x-5=3x+27-10

14-5-x=3x+17

9-x=3x+17

From there, you have to add x to both sides to move -x to another side.

9-x+x=3x+x+17

9=4x+17

minus 17 to move 17 to left side.

9-17=4x+17-17

-8=4x

divide both sides by 4 to cancel out 4

-8/4=4x/4

You get x=-2
