30=6\left(8+3a\right)
Multiply both sides of the equation by 12, the least common multiple of 12,2.
30=48+18a
Use the distributive property to multiply 6 by 8+3a.
48+18a=30
Swap sides so that all variable terms are on the left hand side.
18a=30-48
Subtract 48 from both sides.
18a=-18
Subtract 48 from 30 to get -18.
a=\frac{-18}{18}
Divide both sides by 18.
a=-1
Divide -18 by 18 to get -1.
