x-3-2x-\left(-3\right)=7x-3
To find the opposite of 2x-3, find the opposite of each term.
x-3-2x+3=7x-3
The opposite of -3 is 3.
-x-3+3=7x-3
Combine x and -2x to get -x.
-x=7x-3
Add -3 and 3 to get 0.
-x-7x=-3
Subtract 7x from both sides.
-8x=-3
Combine -x and -7x to get -8x.
x=\frac{-3}{-8}
Divide both sides by -8.
x=\frac{3}{8}
Fraction \frac{-3}{-8} can be simplified to \frac{3}{8} by removing the negative sign from both the numerator and the denominator.
