$a =6$

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

$7a-3 color(red)(-6a)= 3+6acolor(red)(-6a)" "larr$ subtract 6a from both sides

$7a-6a -3 color(blue)(+3)=3color(blue)(+3)" "larr$ add 3 to both sides

$a = 6" "larr$ this is the solution..

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