Answer:
7x-2, -x-6y+16, 5x-3
Step-by-step explanation:
I'm guessing the three expressions are:
1. 3(x+2) + 4(x-2)
2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)
3. 2(4x+3) - 3(x+1)
... 1. 3(x+2) + 4(x-2)
= 3x + 6 + 4x - 8
= 7x - 2
... 2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)
= 2x + 2y - 3x - 3y - y - 8 + 24 - 4y
= -x - 6y + 16
... 3. 2(4x+3) - 3(x+1)
= 8x + 6 - 3x - 3
= 5x - 3
