Answer: The correct option is option third .
Explanation:
The given equation are,
[tex]0.8-4x=-0.4y\\6x+0.4y=4.2[/tex]
In the second equation the like terms are aligned, therefore, we have to aligened only first equation.
The first equation is,
[tex]0.8-4x=-0.4y[/tex]
Subtract 0.8 from both the sides.
[tex]0.8-4x-0.8=-0.4y-0.8[/tex]
[tex]-4x=-0.4y-0.8[/tex]
Add 0.4y on both the sides.
[tex]-4x+0.4y=-0.4y-0.8+0.4y[/tex]
[tex]-4x+0.4y=-0.8[/tex]
So, after aligned the system of equation have two equations.
[tex]-4x+0.4y=-0.8[/tex]
[tex]6x+0.4y=4.2[/tex]
Both equation are show in third option, So third option is correct.
