4x – 9y = 7

–2x + 3y = 4
What number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation?

What number would you multiply the second equation by in order to eliminate the y-terms when adding to the first equation?

What number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation?

It's 2 (to get - 4x & 4x + - 4x = 0)

What number would you multiply the second equation by in order to eliminate the y-terms when adding to the first equation?

It's 3 (to get 9y & - 9y + + 9y =0)

Hope this helps!
