Question

x + 2y = -2-3x +2y = –10O I should add, and the Xs will be eliminated.O I should add, and the Ys will be eliminated.O I should subtract, and the Xs will be eliminated.O I should subtract, and the Ys will be eliminated.

Answer 1

Let's consider the system of equations:

`x+2y=-2`
`-3x+2y=-10`

If we subtract the second one from the first one we'll get

`4x+0=\text{ 8}`

Therefore, if you subtract the equations, the y's will be eliminated
