to solve a system using the additional method, you would need to multiply the first equation by what number in order for the x’s to add out? 3x-y=3, -2x+2y=6

Respuesta :

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]
