How do you solve the system #2x+4y=8# and #x+y=1# by graphing?
please see below
To solve any set of linear equations graphical method isn't much used because it is time consuming but have a look at it.
like the set of values could be
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 .
