# How do you solve the system 2x+4y=8 and x+y=1 by graphing?

Dec 23, 2017

#### Explanation:

To solve any set of linear equations graphical method isn't much used because it is time consuming but have a look at it.
$x + y = 1$ put any 2 distinct values of x to get 2 distinct values of y .
like the set of values could be
$x = 1 y = 0$
$x = 0 y = 1$
do the same for other equation . plot these values on graph .since these are linear equations the graph would show a straight line .
the point at which the lines intersect is common solution .
I designed a graph for same at desmos have a look .
