Question

What is the result of subtracting the second equation from the first?

-2x+y=0
- 7x + 3y = 2

Answer 1

5x - 2y = - 2

Explanation:

Given the 2 equations

- 2x + y = 0 → (1)

- 7x + 3y = 2 → (2)

Subtracting (2) from (1) term by term

- 2x - (- 7x) + y - 3y = 0 - 2, that is

- 2x + 7x - 2y = - 2

5x - 2y = - 2
