Question

What is the result of subtracting the second equation from the first?
8x-4y=-4
-3x+4y=5

Answer 1

You can’t subtract 8x from 4y

Answer 2

Explanation:

`8x - 4y = -4`

`-3x + 4y = 5`

Subtracting the second equation from the first gives us the following:

`(8x - 4y) - (-3x + 4y) = (-4) - (5)`

`8x - 4y + 3x - 4y = -4 - 5`

`11x - 8y = -9`
