Question

X + y = 2, -2x + 4x = 2
System of Equations

Answer 1

`x=1\\y=1`

Explanation:

Solve by substitution:

`x+y=2\\-2x+4x=2`

`2x=2;x+y=2`

Solve
`2x+2` for x:

`2x=2`

`x=2/2`

`x=1`

Substitute 1 for x in
`x+y=2`

`x+y=2`

`1+y=2`

`y=2-1`

`y=1`

`x=1` &
`y=1`

hope this helps...

Answer 2

`- 2x + 4x = 2 \\ 2x = 2 \\ x = 1 \\ \\ 1 + y = 2 \\ y = 1`
