Answer

a=3

Work Step by Step

We need to get the a alone. We need to use multiplication to cancel out division, so we multiply both sides by 5 to get that 10=3a+1. We now cancel out the addition by subtracting 1 on both sides, giving us the equation 9=3a. We finally cancel out multiplication by dividing both sides by 3, giving us an answer of a=3.
