The functions below form a system of linear equations: 7x + 4y = 8

3x + y = 12

Use the elimination method to find the solution to the system (their point of intersection).

You may want to consider these steps:

1) decide: should we eliminate x or y?

2) what do we need to multiply each equation by?

3) do we add the equations, or subtract them?

4) which variable do we solve for?

5) what is the value of that variable?

6) how can we use it to find the other variable? (which equation do we use?)
