You can put this solution on YOUR website!
You have 4 linear equations in 4 variables.
\n" ); document.write( "Use substitutions among the 4 equations to get one pair of equations in the same 2 variables, for example, get 2 equations in x and y.
\n" ); document.write( "Now plug-in a value of x in one of these pair and find y.
\n" ); document.write( "Use that point (x,y) to find w and z that satisfy all 4 equations.
