The answer would be solved like this:
a+b=81, a being white horse, and the var b being bear river.
a-7=b, so we would subtract 7 from 81, then divide by 2.
81-7 = 74, 74/2 = 37, then because we are solving for white horse, add 7.
White horse scored 44 points in the basketball game.
Hope this helps and have a nice day:)
