X=32
Explanation:
When you change sides, if in the left side you are multiplying, when you transfer it to right side you divide. Same thing should be done for addition subtraction.

When we transfered it, it became positive multiplication number
So the correct answer is 2(x^ -11x+25) then
Ok,
8x - amount of boys
7x - amount of girls
8x + 7x = 195
15x = 195
195 / 15 = 13
x = 13
Plug in 13 for x
8 * 13 = 104
7 * 13 = 91
There are 104 boys and 91 girls
Hope this helps!
