x+19.2=2+9x
Multiply 3 and 6.4 to get 19.2.
x+19.2-9x=2
Subtract 9x from both sides.
-8x+19.2=2
Combine x and -9x to get -8x.
-8x=2-19.2
Subtract 19.2 from both sides.
-8x=-17.2
Subtract 19.2 from 2 to get -17.2.
x=\frac{-17.2}{-8}
Divide both sides by -8.
x=\frac{-172}{-80}
Expand \frac{-17.2}{-8} by multiplying both numerator and the denominator by 10.
x=\frac{43}{20}
Reduce the fraction \frac{-172}{-80} to lowest terms by extracting and canceling out -4.
