Question

In a recent golf match, Becky’s score was 5 less than Cathy’s score. Their combined scores totaled 185. Which of the following pairs of equations can be used to determine their scores? Let b represent Becky’s score and c represent Cathy’s score.

Answer 1

B=c-5

c+b=185

so, c+(c-5)=185

2c=190
c=95
b=90

As simple as that.
