\[14-(x+5)=3(x+9)-10\]
1
Remove parentheses.
14−x−5=3(x+9)−1014-x-5=3(x+9)-10

2
Simplify  14−x−514-x-5  to  9−x9-x.
9−x=3(x+9)−109-x=3(x+9)-10

3
Expand.
9−x=3x+27−109-x=3x+27-10

4
Simplify  3x+27−103x+27-10  to  3x+173x+17.
9−x=3x+179-x=3x+17

5
Subtract 99 from both sides.
−x=3x+17−9-x=3x+17-9

6
Simplify  3x+17−93x+17-9  to  3x+83x+8.
−x=3x+8-x=3x+8

7
Subtract 3x3x from both sides.
−x−3x=8-x-3x=8

8
Simplify  −x−3x-x-3x  to  −4x-4x.
−4x=8-4x=8

9
Divide both sides by −4-4.
x=−84x=-\frac{8}{4}

10
Simplify  84\frac{8}{4}  to  22.
x=−2x=-2

Done
