2x-5=25.8
Swap sides so that all variable terms are on the left hand side.
2x=25.8+5
Add 5 to both sides.
2x=30.8
Add 25.8 and 5 to get 30.8.
x=\frac{30.8}{2}
Divide both sides by 2.
x=\frac{308}{20}
Expand \frac{30.8}{2} by multiplying both numerator and the denominator by 10.
x=\frac{77}{5}
Reduce the fraction \frac{308}{20} to lowest terms by extracting and canceling out 4.
