5x-2-\left(-3x\right)=2x-2
To find the opposite of 2-3x, find the opposite of each term.
5x-2+3x=2x-2
The opposite of -3x is 3x.
8x-2=2x-2
Combine 5x and 3x to get 8x.
8x-2-2x=-2
Subtract 2x from both sides.
6x-2=-2
Combine 8x and -2x to get 6x.
6x=-2+2
Add 2 to both sides.
6x=0
Add -2 and 2 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 6 is not equal to 0, x must be equal to 0.
