5\left(x+3\right)=8x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
5x+15=8x
Use the distributive property to multiply 5 by x+3.
5x+15-8x=0
Subtract 8x from both sides.
-3x+15=0
Combine 5x and -8x to get -3x.
-3x=-15
Subtract 15 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-15}{-3}
Divide both sides by -3.
x=5
Divide -15 by -3 to get 5.
