The answer to y=x+6

y=-2x

y=-2x

y=x+6

subsiutte

-2x=y=x+6

-2x=x+6

subtract x from both sides

-3x=6

multiply - 1

3x=-6

diivde 3

x=-2

subsiutte

y=-2 (-2)

y=4

x=-2

y=4

in (x, y) format

(-2,4) is the answer

Y=x+6

y = - 2x

Plug the 2nd into the 1st equation.

y=x+6

-2x = x+6

Subtract x from both sides: - 2x-x=6

Simplify: - 3x = 6

Solve: x = - 2

Plug into the first equation:

y=x+6

y=-2+6

y=4

Verify by putting both into each equation.

y=x+6

y = - 2x

4 = (-2) + 6? True

4 = - 2 (-2) ? True

x=-2, y=4
