48=3\left(x+13\right)
Variable x cannot be equal to -13 since division by zero is not defined. Multiply both sides of the equation by x+13.
48=3x+39
Use the distributive property to multiply 3 by x+13.
3x+39=48
Swap sides so that all variable terms are on the left hand side.
3x=48-39
Subtract 39 from both sides.
3x=9
Subtract 39 from 48 to get 9.
x=\frac{9}{3}
Divide both sides by 3.
x=3
Divide 9 by 3 to get 3.
