Sent a picture of the solution to the problem (s). I sent the formula because I do not know if your calculator has the combination function. You will notice the denominator. I got it by the 2 picks you make and the 3 from what is left over. The 5 is from the total selection.

Answer:
9y + 5x
Step-by-step explanation:
5y + 2y +6x +2y-x
(5 + 2 + 2)y + (6 - 1)x
9y + 5x
1)4x-7=2x+9
Subtract 2x
2x-7= 9
Add 7
2x=16
X= 8
2(8)+9=25
(8,25)
X+y=10
-X-2y=-14
-y= -4
Y=4
X+4=10
X=6
(6,4)
