Hope this helps!
Answer:
Let x and y be the two numbers. Then
yx=57 and x−y=20
Cross multiplying the proportion
5x=7y or y=75x
So, x−y=20
x−75x=20⇒77x−5x=72x=20
⇒x=2140=70
y=75x=75×70=50
So smaller number is 50.
Check :yx=5070=57 and 70−50=20
Expression 1 is the main equation and expression 2 is the more simplified equation from expression 1.
326 + 37g
-287 - 23g
-----------------
38 + 14g
(Though I think 38 is suppose to be 39.)
