Question

Rewrite each expression by combining like terms.

5×y-2xy

&


4q + 2q - 6

Answer 1

5y-2xy

6q-6

Explanation:

For the first expression, we can multiply 5 by y to get 5y. Thats all we can simplify it though, because xy is not equal to x or y.

For the second equation, we can easily add the variables to simplify. 6q-6

Hope this helps!

Answer 2

1)
`5* y-2xy=y(5-2x)`

2)
`4q + 2q - 6=6(q-1)`

Explanation:

1)
`5* y-2xy`

In both terms given in an expression has common variable of 'y', so we can take that common.

The expression will be written as:

`5* y-2xy=y(5-2x)`

2)
`4q + 2q - 6`

In two terms out of three in an expression has common variable of 'q', so we can take that common.

The expression will be written as:

`4q + 2q - 6=2q(2+1)-6`

`=2q(3)-6`

`=6q-6`

`4q + 2q - 6=6(q-1)`
