25+x-3x=4
Subtract 3x from both sides.
25-2x=4
Combine x and -3x to get -2x.
-2x=4-25
Subtract 25 from both sides.
-2x=-21
Subtract 25 from 4 to get -21.
x=\frac{-21}{-2}
Divide both sides by -2.
x=\frac{21}{2}
Fraction \frac{-21}{-2} can be simplified to \frac{21}{2} by removing the negative sign from both the numerator and the denominator.
