Question

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

Answer 1

2

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:

`3 x - y = 3` --- (1)

`-2x + 2y = 6` --- (2)

We will multiply equation (1) by 2 and equation (2) by 3 to cancel the x's.

`2 ( 3x - y = 3 ) =`
`6x - 2 y = 6`

`3 ( -2x + 2 y = 6 ) = -6x + 6y = 36`
