x+10=1.5x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
x+10-1.5x=0
Subtract 1.5x from both sides.
-0.5x+10=0
Combine x and -1.5x to get -0.5x.
-0.5x=-10
Subtract 10 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-10}{-0.5}
Divide both sides by -0.5.
x=\frac{-100}{-5}
Expand \frac{-10}{-0.5} by multiplying both numerator and the denominator by 10.
x=20
Divide -100 by -5 to get 20.
