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