2.5x+21.5=26
Swap sides so that all variable terms are on the left hand side.
2.5x=26-21.5
Subtract 21.5 from both sides.
2.5x=4.5
Subtract 21.5 from 26 to get 4.5.
x=\frac{4.5}{2.5}
Divide both sides by 2.5.
x=\frac{45}{25}
Expand \frac{4.5}{2.5} by multiplying both numerator and the denominator by 10.
x=\frac{9}{5}
Reduce the fraction \frac{45}{25} to lowest terms by extracting and canceling out 5.
