Answer:
234
Step-by-step explanation:
So what we know is that
5x+9x= students
This equation is saying that for every 5 boys there are 9 girls
we can then plug in 364 for the number of students and add like terms
This means that 14x=364
this means that x=26
This means that there are 26 sets of 5 boys and 9 girls
this means that there are
130 boys
234 girls
x = -2
-2 + 2y = -12
add 2 to both sides: 2y = -10
divide by 2 on both sides: y = -5
when x = -2, y = -5
