Question

What is the result of subtracting the secound equation from the first -4x-2y=-2 x-2y=9

Answer 1

When we subtract the second equation x-2y=9 from the first equation 4x-2y=-2, we get the value of x = 11/5.

Therefore, the required result is:

x = 11/5

Explanation:

Given

The first equation

`-4x-2y=-2`

The second equation

`x-2y=9`

Let us subtract the second equation from the first equation

`-4x-2y=-2`

`-`

`\:\underline{x-2y=9}`

`-4x - 2y - (x - 2y) = -2 - 9`

`-4x -2y -x + 2y = -2-9`

`-5x = -11`

divide both sides by -5

`(-5x)/(-5)=(-11)/(-5)`

Simplify

`x=(11)/(5)`

Thus, when we subtract the second equation x-2y=9 from the first equation 4x-2y=-2, we get the value of x = 11/5.

Therefore, the required result is:

x = 11/5
