Hey there!☺
When you are solving an equation, it is important to use <em>inverse</em> operations. You will need to use the <em>inverse</em> operations on both sides of the equation. And it is also important to isolate the variable. After you do that, you will need to reverse it up. The way to do all of this is using the <em>inverse</em>.
To solve an equation, you use <u>inverse</u> operations.
Hope this helps!

Ok, from your picture, it looks like you have a square and a right triangle next to each other
one of the definition of a square is that all 4 sides are equal, and its given to you that the square has a side length of 3
since the triangle shares a side with the square, that means that shared side has a length of 3
ok, now how about determining the unknown length x
well the base has a length of 5, but you also know that when you add the length of the square side plus x, you should get 5
3+x = 5
and you can solve for x (subtract 3 from both sides)
x=2
now how about determining side length y
well since you know this is a right triangle, you can apply pythagorean theorem
where C is the hypothenuse of the triangle, or the longest side
when you substitute the known values (3 and x)
you get
3^2 + x^2 = y^2
since you already know x=2
3^2 +2^2 = y^2
and you can solve for y
any questions?
