Answer:
2
Step-by-step explanation:
In order to solve a system using the additional method, we would need to multiply the first equation by '2' in order for the x’s to add out.
We have the following equations:
[tex] 3 x - y = 3 [/tex] --- (1)
[tex] -2x + 2y = 6 [/tex] --- (2)
We will multiply equation (1) by 2 and equation (2) by 3 to cancel the x's.
[tex] 2 ( 3x - y = 3 ) = [/tex] [tex] 6x - 2 y = 6 [/tex]
[tex] 3 ( -2x + 2 y = 6 ) = -6x + 6y = 36 [/tex]
