6x-4-\left(x-3\right)=8
Use the distributive property to multiply 2 by 3x-2.
6x-4-x-\left(-3\right)=8
To find the opposite of x-3, find the opposite of each term.
6x-4-x+3=8
The opposite of -3 is 3.
5x-4+3=8
Combine 6x and -x to get 5x.
5x-1=8
Add -4 and 3 to get -1.
5x=8+1
Add 1 to both sides.
5x=9
Add 8 and 1 to get 9.
x=\frac{9}{5}
Divide both sides by 5.
