1.47-0.15x-0.1x=0.5\times 0.1x
Multiply 0.15 and 9.8 to get 1.47.
1.47-0.25x=0.5\times 0.1x
Combine -0.15x and -0.1x to get -0.25x.
1.47-0.25x=0.05x
Multiply 0.5 and 0.1 to get 0.05.
1.47-0.25x-0.05x=0
Subtract 0.05x from both sides.
1.47-0.3x=0
Combine -0.25x and -0.05x to get -0.3x.
-0.3x=-1.47
Subtract 1.47 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-1.47}{-0.3}
Divide both sides by -0.3.
x=\frac{-147}{-30}
Expand \frac{-1.47}{-0.3} by multiplying both numerator and the denominator by 100.
x=\frac{49}{10}
Reduce the fraction \frac{-147}{-30} to lowest terms by extracting and canceling out -3.
