Simplify each expression.

1.) 4.2x + 8.1x + 1.8x - 2.1x

2.) x + 2 (x - y)

3.) (5x + y) - (4x - 9)

4.) 33.7y + 8.4 - 2.04y

(1) = 6x+6 (2) =3x-2y (3) = x+y+9 (4) = 31.66y+8.4

I hope this helps you

1) x (4,2+8,1+1,8+2,1)=16,2x

2) x+2x-2y=3x-2y

3) 5x+2y-4x+9=x+2y+9

4) y (33,7-2,04)+8,4=31,66y+8,4
