15=5\left(x+1\right)
Variable x cannot be equal to -1 since division by zero is not defined. Multiply both sides of the equation by x+1.
15=5x+5
Use the distributive property to multiply 5 by x+1.
5x+5=15
Swap sides so that all variable terms are on the left hand side.
5x=15-5
Subtract 5 from both sides.
5x=10
Subtract 5 from 15 to get 10.
x=\frac{10}{5}
Divide both sides by 5.
x=2
Divide 10 by 5 to get 2.
