# How do you simplify #(6) (3x-y) - (4)(2x+y)#?

##### 1 Answer

#### Answer:

- Multiply the factors into each other using
#x(a+b) = (ax+bx)#

This will give us the answer

#### Explanation:

To handle this type of multiplication, use this rule:

This gives us:

Remember to put parentheses around the factors after a minus sign! If you don't you might end up with a different answer if you don't keep your tounge in your mouth.

Eventually 10(x-y)
