x+8=4x
Multiply both sides of the equation by 2.
x+8-4x=0
Subtract 4x from both sides.
-3x+8=0
Combine x and -4x to get -3x.
-3x=-8
Subtract 8 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-8}{-3}
Divide both sides by -3.
x=\frac{8}{3}
Fraction \frac{-8}{-3} can be simplified to \frac{8}{3} by removing the negative sign from both the numerator and the denominator.
