8x + 4y= 12
2x + y= 3

In order to solve for both x and y, we need to use the substitution property, where we replace a variable with what we solved for.

Let's solve for y first. Equation (1st one): 8x + 4y = 12. To isolate y, we can first subtract 8x from both sides, and then divide all terms by 4.

Then, we can solve for x. Let's take the second equation: 3x + y = 3. We take what we solved for in the previous step and plug it into this equation.

Both equations are also the same, so the solution = all real numbers for x.
