Someone help me with this 2x + 3y = 6
x + 2y = 5

y=4,x=-3

Step-by-step explanation:

2x +3y=61

x +2y=52

multiply equation 1 by 1

multiply equation 2 by 2

2x+3y=6×1

x+2y=5×2

2x+3y=63

2x+4y=104

subtract eqtn 3 from 4

4y-3y=10-6

:. y=4

put y=4 into eqtn 2

x+2y=5

x+2(4)=5

x+8=5

x=5-8

X=-3

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
