WebSo x equals negative 1 is right over here. x is equal to negative 1. And our function graph is right at 6 when f is equal to negative 1. So we can say that f of negative 1 is equal to 6. … WebSo lets recap, we add or subtract a variable to cancel out the other variable in elimination. If 4x-2y=14 was actually 4x+2y=14, and do what we did, it wouldn't cancel out the first equation. To get it to cancel out 2y, we multiply the equation by (-1) by both sides. -1 (4x + 2y) = (14)-1. Turns into:
