Answer:

Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

What is the resulting equation when the expression for y in the second equation is substituted into the first equation? 3x y = 1

Natali5045456 [20]

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.

<h3>How to solve equations?</h3>

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 $x=5$ .
