Look at the variable you are lookig for. It's x.
If you had a number for x and you wanted to know what the left sides is equal to you would
1. multiply x by 3
2. subtract 19
In order to solve for x, do the opposite of the operations above in the opposite order.
So start by 
1. add 19
2. divide by 3
