0.36\left(x+60\right)=12+x
Variable x cannot be equal to -60 since division by zero is not defined. Multiply both sides of the equation by x+60.
0.36x+21.6=12+x
Use the distributive property to multiply 0.36 by x+60.
0.36x+21.6-x=12
Subtract x from both sides.
-0.64x+21.6=12
Combine 0.36x and -x to get -0.64x.
-0.64x=12-21.6
Subtract 21.6 from both sides.
-0.64x=-9.6
Subtract 21.6 from 12 to get -9.6.
x=\frac{-9.6}{-0.64}
Divide both sides by -0.64.
x=\frac{-960}{-64}
Expand \frac{-9.6}{-0.64} by multiplying both numerator and the denominator by 100.
x=15
Divide -960 by -64 to get 15.
