8=1\times 0.5\left(x+5\right)
Variable x cannot be equal to -5 since division by zero is not defined. Multiply both sides of the equation by x+5.
8=0.5\left(x+5\right)
Multiply 1 and 0.5 to get 0.5.
8=0.5x+2.5
Use the distributive property to multiply 0.5 by x+5.
0.5x+2.5=8
Swap sides so that all variable terms are on the left hand side.
0.5x=8-2.5
Subtract 2.5 from both sides.
0.5x=5.5
Subtract 2.5 from 8 to get 5.5.
x=\frac{5.5}{0.5}
Divide both sides by 0.5.
x=\frac{55}{5}
Expand \frac{5.5}{0.5} by multiplying both numerator and the denominator by 10.
x=11
Divide 55 by 5 to get 11.
