9x + y = 9 3x + 3y = -12

x = 13/8

y = -45/8

Step-by-step explanation:

9x + y = 9

3x + 3y = -12

Divide the second equation by 3

x+y = -4

Multiply this by -1

-x -y = 4

Add this to the first equation to eliminate y

9x + y = 9

-x -y = 4

8x +0 = 13

Divide by 8

8x/8 = 13/8

x = 13/8

Now find y

x+y = -4

13/8 +y = -4

Subtract 13/8 from each side

13/8 -13/8 +y = -4-13/8

y = -32/8 - 13/8

y = -45/8

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female
