\frac{10}{5}+\frac{12}{5}=\frac{1}{10}x
Convert 2 to fraction \frac{10}{5}.
\frac{10+12}{5}=\frac{1}{10}x
Since \frac{10}{5} and \frac{12}{5} have the same denominator, add them by adding their numerators.
\frac{22}{5}=\frac{1}{10}x
Add 10 and 12 to get 22.
\frac{1}{10}x=\frac{22}{5}
Swap sides so that all variable terms are on the left hand side.
x=\frac{22}{5}\times 10
Multiply both sides by 10, the reciprocal of \frac{1}{10}.
x=\frac{22\times 10}{5}
Express \frac{22}{5}\times 10 as a single fraction.
x=\frac{220}{5}
Multiply 22 and 10 to get 220.
x=44
Divide 220 by 5 to get 44.
