Answer 5

Elimination means that you will need to multiply th equations by a factor so that way if you add them or subtract them, they will elimate one varaible, and let you solve for the other variable.

Answer 6

So, what number can you multiply the first equation by to get -3y.

So basically, lets call this number x and we have just y. So for what value of x is this true:

\(\sf xy = -3y\)

What should x be equal to?

so that way we can multiply x to the first equation which is \(\sf y+z=6\)
