5=0.2\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.
5=0.2x+0.2
Use the distributive property to multiply 0.2 by x+1.
0.2x+0.2=5
Swap sides so that all variable terms are on the left hand side.
0.2x=5-0.2
Subtract 0.2 from both sides.
0.2x=4.8
Subtract 0.2 from 5 to get 4.8.
x=\frac{4.8}{0.2}
Divide both sides by 0.2.
x=\frac{48}{2}
Expand \frac{4.8}{0.2} by multiplying both numerator and the denominator by 10.
x=24
Divide 48 by 2 to get 24.
