Answer:
x = ± 2
Step-by-step explanation:
Given
16 - 2x² = - 64 ( subtract 16 from both sides )
- 2x² = - 80 ( divide both sides by - 2 )
x² = 40 ( take the square root of both sides )
x = ± 
= ± 
= ± 2

Ok,
8x - amount of boys
7x - amount of girls
8x + 7x = 195
15x = 195
195 / 15 = 13

Plug in 13 for x
8 * 13 = 104
7 * 13 = 91
There are 104 boys and 91 girls
Hope this helps!
