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.
