3\times 0.8x+85=320+9
Divide 9 by 3 to get 3.
2.4x+85=320+9
Multiply 3 and 0.8 to get 2.4.
2.4x+85=329
Add 320 and 9 to get 329.
2.4x=329-85
Subtract 85 from both sides.
2.4x=244
Subtract 85 from 329 to get 244.
x=\frac{244}{2.4}
Divide both sides by 2.4.
x=\frac{2440}{24}
Expand \frac{244}{2.4} by multiplying both numerator and the denominator by 10.
x=\frac{305}{3}
Reduce the fraction \frac{2440}{24} to lowest terms by extracting and canceling out 8.
