Question 1048351
The two equations are equivalent and can be represented with the same line, graphically.  


The simplified form of the equation is the best one to use.
{{{2y+x=4}}}
{{{2y=-x+4}}}
{{{y=-x/2+2}}}-------the equation has an infinite number of solutions, all being points on the line.  This could also be given as a general ordered (x,y) pair,  (x, -x/2+2 ).
