Let's start with 5 squared. 5 squared, or just squared in general, represents the number behind it times itself.
[tex]5^2~or~ 5*5 = 25[/tex]
Now, add 3
[tex]25 + 3 = 28[/tex]
Next, subtract 1
[tex]28 - 1 = 27[/tex]
Now, you must divide, because the line under the first equation represents division, or a fraction. For this case, division. Before dividing your result, 27, by y, the second equation, you first want to solve equation 2, y.
[tex]\frac{18}{2} = 9[/tex]
Lastly, divide x by y, 27 divided by 9
[tex]\frac{27}{9} = 3[/tex]
The problem is solved! The final answer is 3
