Mathematics

Rearranging the first equation gives:

y=3x-2

Substituting this into the other equation gives:

y+x=-6
\\(3x-2)+x=-6
\\4x-2=-6
\\4x=-4 \\x=-1

If x=-1:

y+(-1)=-6
\\y=-5

So x=-1, y=-5

Y - 3x = -2 ⇒ 2y - 6x = -4
y +  x = -6 ⇒ <u>2y + 2x = -12</u>
                            -<u>8x</u> = <u>8</u>
                             -8    -8
                               x = -1
                    y - 3(-1) = -2
                         y + 3 = -2
                         <u>    -3     -3</u>
                               y = -5
                         (x, y) = (-1, -5)
