Explanation:
Information given in the question:
Let x be the total scored in the game.
Contribution of Brian in the game =
![\displaystyle(x)/(10)](https://img.qammunity.org/2019/formulas/mathematics/high-school/7cu8cepb4eso5go7erxaamyrjrdrq5wm4g.png)
Contribution of Joe in the game =
![\displaystyle(x)/(4)](https://img.qammunity.org/2019/formulas/mathematics/high-school/dwu1qz6ildr2b4rf41mpred1m7oo4bi6tp.png)
Total contribution of Brian and Joe in the game = 21
According to the question, the following equation can be used to represent the situation:
![\displaystyle(x)/(10) + \displaystyle(x)/(4) = 21](https://img.qammunity.org/2019/formulas/mathematics/high-school/tj620wnxvnd441lb3opnhncwo6pmta3qfd.png)
![\displaystyle(7x)/(20) = 21\\\\ 7x = 20* 21\\x = 60](https://img.qammunity.org/2019/formulas/mathematics/high-school/ft9cavctoihl5f0kz03becvb459m5uakz1.png)
Thus, the total score of the game was 60.
