Question

A system of equations is shown below.
8x - 2y = -4
4x - y = -2

Answer 1

Explanation:

Solve this system using elimination by addition and subtraction:

Multiplying the second equation by -2 yields the modified system

8x - 2y = -4

-8x + 2y = +4

Adding these together, we get 0 + 0 = 0 (This is always true.)

There are an infinite number of solutions.
