9(2-11x-y)=
(16+7x+8y)*2=

Answer 1

1.=21+3x
2.=18-2x
3.=15-5x
4.=6x-ax
5.=36-132x-12y
6.=90+12x+24y
7.=12+6x
8.=45-15x
9.=12-4x
10.=7x-ax
11.=18-99x-9y
12.=32+14x+16y

Answer 2

(7+x)*3=21+3x

(9-x)*2=18-2x

5(3-x)=15-5x

x(6-a)=6x-ax

12(3-11x-y)=36-132x-12y

(15+2x+4y)*6=90+12x+24y

(2+x)*6=12+6x

(3-x)*15=45-15x

4(3-x)=12-4x

x(7-a)=7x-ax

9(2-11x-y)=18-99x-9y

(16+7x+8y)*2=32+14x+16y
