Steps to solve:
2x + 3y = 36 when y = 6
~Substitute
2x + 3(6) = 36
~Simplify
2x + 18 = 36
~Subtract 18 to both sides
2x = 18
~Divide 2 to both sides
x = 9

<em>Explanation for a: Making the equations</em>
Assuming h is the amount of half-page ads and f is the amount of full page ads, we can create the equations since the total cost will be 800$, and we have a total of 13 ads.
<em>Explanation for b: Solving for h</em>
We can now solve for one of the variables using elimination. Let’s multiply the expression by -75.
Great! Now let’s add the equations.
Adding these equations, we get
Divide both sides by -35, and we get .
<em>Explanation for c: Solving for f</em>
We can now substitute h inside the equation .
