Step-by-step explanation:
<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
.

In problem number 1, the answer is 2. because if Aneesha multiply the first equation with 5, 2y will become 10y and if she multiply the sencond equation with 2, 5y will become 10y and 10y from both equations cancel out each other.
in problem number 2, the answer is 2. it's the same logic as number 1. if you multiply 0.5x with 2, it will become 1 and cancel out with x from first equation.
