Answer:

[tex](3,-1)[/tex]

Step-by-step explanation:

[tex]y=-x+2\\x-3y=6[/tex]

We are given the y is equal to -x+2 so we fill in the value of y into the second equation to find x

[tex]x-3(-x+2)=6[/tex]

Distribute

[tex]x+3x-6=6[/tex]

Combine like terms

[tex]4x-6=6[/tex]

Add 6 to both sides

[tex]4x=12[/tex]

Divide 4 on both sides

[tex]x=3[/tex]

Now that we know the value of x we fill in the value of x into either equation to find y

[tex]y=-3+2\\y=-1[/tex]

So since x is 3 and y is -1 we can write it as an ordered pair (3,-1)
