10\times 3+10a\times \frac{1}{2}=2\times 11
Variable a cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 10a, the least common multiple of a,2,5a.
30+10a\times \frac{1}{2}=2\times 11
Multiply 10 and 3 to get 30.
30+5a=2\times 11
Multiply 10 and \frac{1}{2} to get 5.
30+5a=22
Multiply 2 and 11 to get 22.
5a=22-30
Subtract 30 from both sides.
5a=-8
Subtract 30 from 22 to get -8.
a=\frac{-8}{5}
Divide both sides by 5.
a=-\frac{8}{5}
Fraction \frac{-8}{5} can be rewritten as -\frac{8}{5} by extracting the negative sign.
