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