1) 2(3-x) - (8+x)= 6 - 2x - 8 - x= -3x - 2
2) -4(y+5) + (12-y)= -4y - 20 + 12 - y= -5y - 8
3) -(7-x) + 4(x-5)= -7 + x + 4x - 20= 5x - 27
4) -9(y-4) - (12+y)= -9y + 36 - 12 - y= -10y + 24
1) 2(3-x) - (8+x)
= 6 - 2x - 8 - x
= -3x - 2
2) -4(y+5) + (12-y)
= -4y - 20 + 12 - y
= -5y - 8
3) -(7-x) + 4(x-5)
= -7 + x + 4x - 20
= 5x - 27
4) -9(y-4) - (12+y)
= -9y + 36 - 12 - y
= -10y + 24
