1.25+45-x=0.1x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
46.25-x=0.1x
Add 1.25 and 45 to get 46.25.
46.25-x-0.1x=0
Subtract 0.1x from both sides.
46.25-1.1x=0
Combine -x and -0.1x to get -1.1x.
-1.1x=-46.25
Subtract 46.25 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-46.25}{-1.1}
Divide both sides by -1.1.
x=\frac{-4625}{-110}
Expand \frac{-46.25}{-1.1} by multiplying both numerator and the denominator by 100.
x=\frac{925}{22}
Reduce the fraction \frac{-4625}{-110} to lowest terms by extracting and canceling out -5.
