2x=\frac{1}{8}+5
Add 5 to both sides.
2x=\frac{1}{8}+\frac{40}{8}
Convert 5 to fraction \frac{40}{8}.
2x=\frac{1+40}{8}
Since \frac{1}{8} and \frac{40}{8} have the same denominator, add them by adding their numerators.
2x=\frac{41}{8}
Add 1 and 40 to get 41.
x=\frac{\frac{41}{8}}{2}
Divide both sides by 2.
x=\frac{41}{8\times 2}
Express \frac{\frac{41}{8}}{2} as a single fraction.
x=\frac{41}{16}
Multiply 8 and 2 to get 16.
