Can someone me and explain, the answer is on the blue paper

First thing you do is make both sides of the equation fractions which would make it

15/100 + 44/100 = x/20 + 44/100

Then you’d cancel out the 44/100 since there are one of those on each side of the equation. That would leave you at

15/100 = x/20

You then need to get common denominators. 20*5=100 would give you a common denominator of 100, and anything you do to the denominator you do to the numerator so you’d also multiply x by 5 (5x):

15/100 = 5x/100

Then cancel out the 100 since there is a 100 as a denominator on both sides of the equation

15 = 5x

For there you divide both sides by 5 to get x by itself (15/5=3 and 5x/5=x) which would leave you with

3 = x

I’m sry if this didn’t help I’m not great at explaining math equations
