Answer:
a ) 9x + 6y
b ) 8a + 8b
c ) 4u + 3v
d ) 8p + 8q
e ) 6m + 8n
f ) 7u + 12v
g ) 11b + 5c
h ) 2a - b
i ) 8b
j ) 7p
Step-by-step explanation:
By grouping like terms, just treat them as normal math problems.
For example :
a ) 2x + 6y + 7x =
Group like terms :
2x + 7x + 6y =
( I've moved the 7x so that it's aligned with 2x )
This makes it easier to solve.
2x is 2 x es.
Just imagine x as points.
So if 7x ( note points ) + 2x ( note points ) means
7 points + 2 points = 9 points.
After that, remember to turn "points" into x
While y is another term, it could be any number in the world.
So let's treat it as phones and computers?
x = phones
y = computers.
SO if you have 7 phones + 2 phones + 6 computers,
You will have 9 phones and 6 computers.
Then turn them back into x and ys'
So the answer is 9x+6y.
Implement the same rule in other equations, and you will get the answer above!
Hope this answer helped :)
Answer:
- 2x+7x+6y
= 9x+6
- 3a+5a+8b
= 8a+8b
- 6u-2u+3v
=4u+3v
- 9p-p+8q
=8p+8q
- 2m+4m+5n+3n
=2m+2n
- 6u+u+9v+3v
5u+6v
- 8b+3b+7c-2c
= 5b-5c
- a+a+2b+6b
= 2a+8b
- 5a-5a+2b+6b
= 8b
- 9p+2p+3q-3q
= 11p
