Benny and Emmet have 135 altogether. Emmet has 53 more than Benny. How much does Benny have?

 

Benny = B, Emmet = E

We know that B + E = 135 and E = B + 53

 

This turns into a simple substitution

B + (B + 53) = 135

2B + 53 = 135

2B = 82

B = 41

 

Benny has 41

 

Check:

41 + (41 + 53) = 41 + 94 = 135
