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
[tex]-4x-2y=-2[/tex]
The second equation
[tex]x-2y=9[/tex]
Let us subtract the second equation from the first equation
[tex]-4x-2y=-2[/tex]
[tex]-[/tex]
[tex]\:\underline{x-2y=9}[/tex]
[tex]-4x - 2y - (x - 2y) = -2 - 9[/tex]
[tex]-4x -2y -x + 2y = -2-9[/tex]
[tex]-5x = -11[/tex]
divide both sides by -5
[tex]\frac{-5x}{-5}=\frac{-11}{-5}[/tex]
Simplify
[tex]x=\frac{11}{5}[/tex]
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
