Question

Rewrite each expression by combining like terms.

Answer 1

Answer:

1) $5\times y-2xy=y(5-2x)$

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

Step-by-step explanation:

1) $5\times y-2xy$

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

The expression will be written as:

$5\times y-2xy=y(5-2x)$

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:

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

$=2q(3)-6$

$=6q-6$

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

Answer 2

Answer:

5y-2xy

6q-6

Step-by-step 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!
