3x+97.5-3.9x=83.1
Use the distributive property to multiply 25-x by 3.9.
-0.9x+97.5=83.1
Combine 3x and -3.9x to get -0.9x.
-0.9x=83.1-97.5
Subtract 97.5 from both sides.
-0.9x=-14.4
Subtract 97.5 from 83.1 to get -14.4.
x=\frac{-14.4}{-0.9}
Divide both sides by -0.9.
x=\frac{-144}{-9}
Expand \frac{-14.4}{-0.9} by multiplying both numerator and the denominator by 10.
x=16
Divide -144 by -9 to get 16.
