Question

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

Answer 1

Answer:

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

Step-by-step 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

$\frac{-5x}{-5}=\frac{-11}{-5}$

Simplify

$x=\frac{11}{5}$

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
