3x-6-\left(x-5\right)=13
Use the distributive property to multiply 3 by x-2.
3x-6-x-\left(-5\right)=13
To find the opposite of x-5, find the opposite of each term.
3x-6-x+5=13
The opposite of -5 is 5.
2x-6+5=13
Combine 3x and -x to get 2x.
2x-1=13
Add -6 and 5 to get -1.
2x=13+1
Add 1 to both sides.
2x=14
Add 13 and 1 to get 14.
x=\frac{14}{2}
Divide both sides by 2.
x=7
Divide 14 by 2 to get 7.
