Answer:
Boys equal 189 and girls equal 108
Explanation:
Let b = the number of boys
Let g = the number of girls
b + g = 297
Rewrite as g = 297 - b
b =
g Multiply both sides by 9
4b = 7g Substitute 297 - b for g
4b = 7(297 -b) Distribute the 7
4b = 2079 - 7b Add 7 b to both sides
11b = 2097 Divide both sides by 11
b = 189
There are 189 boys.
g = 297 - b Substitute 189 for b to solve for g
g = 297 - 189
g = 180
The number of girls is 108.
