3x+7=5x-8
Multiply 4 and 2 to get 8.
3x+7-5x=-8
Subtract 5x from both sides.
-2x+7=-8
Combine 3x and -5x to get -2x.
-2x=-8-7
Subtract 7 from both sides.
-2x=-15
Subtract 7 from -8 to get -15.
x=\frac{-15}{-2}
Divide both sides by -2.
x=\frac{15}{2}
Fraction \frac{-15}{-2} can be simplified to \frac{15}{2} by removing the negative sign from both the numerator and the denominator.
