# How do you solve 7a-3=3+6a?

Oct 5, 2016

$a = 6$

#### Explanation:

To solve an equation you need to have all the variable on one side and the numbers on the other side.

$7 a - 3 \textcolor{red}{- 6 a} = 3 + 6 a \textcolor{red}{- 6 a} \text{ } \leftarrow$ subtract 6a from both sides

$7 a - 6 a - 3 \textcolor{b l u e}{+ 3} = 3 \textcolor{b l u e}{+ 3} \text{ } \leftarrow$ add 3 to both sides

$a = 6 \text{ } \leftarrow$ this is the solution..

The solution is the value of a which makes the equation true.
