Answer:
x=-2
Step-by-step 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
