After putting the value of y from the second equation to the first equation, the resultant equation is [tex]x=5[/tex].

GIven:

The equations are:

[tex]3x + y = 1\\ y = 6 - 4x[/tex]

It is required to put the value of y from second equation to the first equation.

The value of y from the second equation is,

[tex] y = 6 - 4x[/tex]

Now, put this value of y in the first equation as,

[tex]3x + y = 1\\ 3x+(6 - 4x)=1\\ 3x+6-4x=1\\ -x=-5\\ x=5[/tex]

Therefore, after putting the value of y from the second equation to the first equation, the resultant equation is [tex]x=5[/tex].
