Y=-2x

Y=-4x+6

Solve each system by substitution

y = - 2x

y = - 4x + 6. Set the equations equal to each other because they both equal y.

-2x = - 4x + 6. Add 4x to each side.

2x = 6. Divide each side by 2.

x = 3. Substitute 3 for x in one of the first equations to get the y value.

y = - 2 (3)

y = - 6.

To ensure these are the correct numbers, let's plug - 6 and 3 back into one of the equations.

-6 = - 2 (3)

-6 = - 6

x = 3 and y = - 6 are correct.
