There were 6075 adults and children at a stadium. The ratio of the number of girls to the number of boys was 8:7. The number of adults was 4755 more than the number of boys and 4695 more than the number of girls. How many children were there altogether?
+36916 g/b = 8/7
g = 8/7 b
a = b + 4755 and a = g + 4695 equate the 'a' definitions
b + 4755 = g + 4695 now sub in the red equation
b + 4755 = 8/7 b + 4695
b = 420 then g = 480 <===== add together
