Question

_

Answer 1

multiply everything in the bottom equation by -1 to go from 3x + 2y = 6 to -3x - 2y = -6

Answer 2

we now have this system

4x + 2y = 10
-3x - 2y = -6

Answer 3

do you see how to finish up?

Answer 4

1x = 4 ---> x = 4

Answer 5

you then use that to find y

Answer 6

you can only pick one equation to save time

however, I like that line of thinking since x = 4 satisfies both

Answer 7

solve 16 + 2y = 10 for y to get y = ???

Answer 8

notice how it works for 12 + 2y = 6 as well


12 + 2y = 6


12 + 2y = 6
-12 -12


2y = -6


y = -6/2


y = -3

Answer 9

either way, x = 4 and y = -3

Answer 10

you too
