Simplify 3(-x + y). anyone know how to simplify this correctly?

To simplify 3( -x + y ), we can use the distributive property.

The distributive property states that

a( b + c ) = ab + ac

Basically the a is distributed to the terms inside the parenthesis, the a is multiplied by b and added to a multiplied by c

For this problem 3 ( -x + y), the 3 is like a. It is outside the parenthesis and needs to be distributed.

So multiplied is 3 * -x + 3 *y

= -3x + 3y
