Y= 5x + 2
For each category you plug it into the equation,
7= (5x1) + 2
12= (5x2) + 2
When given a value of the variable, we replace each instance of the variable in the problem with that number. In this case, the expression becomes:

After this, we merely need to simplify the answer.


Simplifying 12/2 gives us the answer 6.
