a+20+6=3\times 3
Variable a cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 6a, the least common multiple of 6a,a,2a.
a+26=3\times 3
Add 20 and 6 to get 26.
a+26=9
Multiply 3 and 3 to get 9.
a=9-26
Subtract 26 from both sides.
a=-17
Subtract 26 from 9 to get -17.
