A cricket scoreboard uses code: each run by Rohit is r and each run by Virat is v. Over three overs the additions were 4r + 3v, 2r + 5v, and 6r + v. After collecting like terms, what is the coefficient of r in the total?

Question

Accepted Answer

12. r-terms are like: 4r + 2r + 6r = 12r. (v-terms total 9v.) Coefficient of r is 12.

A cricket scoreboard uses code: each run by Rohit is $r$ and each run by Virat is $v$ .
Over three overs the additions were $4 r + 3 v, 2 r + 5 v$ , and $6 r + v$ .
