Question

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

Answer 1

b=c-5
b+c=185

You would then plug c-5 into b for the 2nd equation so you would get c-5+c=185 --> 2c-5=185 --> 2c=190 --> c=95
the you could plug c into the 1st equation to get:
b=95-5 --> b=90
