Question

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

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

​

Answer 1

11x - 8y = -9

Answer 2

`11x-8y=-9`

Explanation:

we have

`8x-4y = -4` ----> First equation

`-3x+4y=5` ----> Second equation

we know that

To subtract the 2nd equation from the first, negate all three of the second equation terms: 3x-4y=-5

and then adds this result with the first equation

`8x-4y = -4\\3x-4y=-5\\-------\\8x+3x-4y-4y=-4-5\\11x-8y=-9`
