Solving systems by elimination (y=-x+1)(y=4x-14)

y = -x + 1

y = 4x - 14

To solve this system via elimination, we would need to multiply the top equation by 4, and then add both equations.

4(-x + 1)

-4x + 4

Now we're left with two equations:

4y = -4x + 4

y = 4x - 14

Add both equations.

5y = -10

Divide both sides by 5.

Because we have a constant value for y, we can solve for x:

y = -x + 1

-2 = -x + 1

Add x to both sides.

x - 2 = 1

Add 2 to both sides.

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
