58.5x+1.49-74.5x=2.5
Use the distributive property to multiply 74.5 by 0.02-x.
-16x+1.49=2.5
Combine 58.5x and -74.5x to get -16x.
-16x=2.5-1.49
Subtract 1.49 from both sides.
-16x=1.01
Subtract 1.49 from 2.5 to get 1.01.
x=\frac{1.01}{-16}
Divide both sides by -16.
x=\frac{101}{-1600}
Expand \frac{1.01}{-16} by multiplying both numerator and the denominator by 100.
x=-\frac{101}{1600}
Fraction \frac{101}{-1600} can be rewritten as -\frac{101}{1600} by extracting the negative sign.
