Question

What is the resulting equation when the expression for y in the second equation is substituted into the first equation? 3x y = 1 y = 6 - 4x 7x 6 = 1 -x 6 = 1 x 6 = 1.

Answer 1

After putting the value of y from the second equation to the first equation, the resultant equation is $x=5$.

GIven:

The equations are:

$3x + y = 1\\ y = 6 - 4x$

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

How to solve equations?

The value of y from the second equation is,

$y = 6 - 4x$

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

$3x + y = 1\\ 3x+(6 - 4x)=1\\ 3x+6-4x=1\\ -x=-5\\ x=5$

Therefore, after putting the value of y from the second equation to the first equation, the resultant equation is $x=5$.
