10x-5=7x-1+10+x
Combine 6x and 4x to get 10x.
10x-5=7x+9+x
Add -1 and 10 to get 9.
10x-5=8x+9
Combine 7x and x to get 8x.
10x-5-8x=9
Subtract 8x from both sides.
2x-5=9
Combine 10x and -8x to get 2x.
2x=9+5
Add 5 to both sides.
2x=14
Add 9 and 5 to get 14.
x=\frac{14}{2}
Divide both sides by 2.
x=7
Divide 14 by 2 to get 7.
