Answer:

20. 2x+y

21. 4

22. x+y

Step-by-step explanation:

20. 9x+2y - x-2y find your LCM

4 4

=(9x+2y)-(x-2y) clear bracket

4

=9x+2y-x+2y collect terms

4

=9x-x+2y+2y

4

=8x+4y factorize

4

=4(2x+y)

4

=2x+y

with this, you will understand the following

21. 4x + 8y

x+2y x+2y

=4x+8y

x+2y

=4(x+2y)

x+2y

=4

22. 2x-y + 2x+5y

4 4

=2x-y+2x+5y

4

=4x+4y

4

=4(x+y)

4

=x+y
