3\times 10+\frac{a}{3.4}=7\times 6
Multiply both sides by 6.
30+\frac{a}{3.4}=7\times 6
Multiply 3 and 10 to get 30.
30+\frac{a}{3.4}=42
Multiply 7 and 6 to get 42.
\frac{a}{3.4}=42-30
Subtract 30 from both sides.
\frac{a}{3.4}=12
Subtract 30 from 42 to get 12.
a=12\times 3.4
Multiply both sides by 3.4.
a=40.8
Multiply 12 and 3.4 to get 40.8.
