I feel like I always ask for help :/ but can someone answer this please, thanks
Maria wants to solve the following system using the elimination method:

4x + 9y = 59
x + y = 17

What number should the equation x + y = 17 be multiplied by to eliminate y? (4 points)


4

−4

9

−9* i think its this one

Respuesta :

You are correct. You multiply both sides of the second equation by -9 so that the y turns into -9y. That way you add it to the +9y in the first equation to get 0y (the y terms cancel afterward). Nice work.
