Could you please use this as an example to solve each system by substitution method and tell if the equations are independent, dependent or inconsistent?
\n" ); document.write( "Thank you.
\n" ); document.write( "2x-y=4
\n" ); document.write( "2x-y=3
\n" ); document.write( "------------
\n" ); document.write( "Solve the 1st equation for y to get: y = 2x-4
\n" ); document.write( "Substitute that into the 2nd equation to solve for \"x\":
\n" ); document.write( "2x-(2x-4) = 3
\n" ); document.write( "4 = 3
\n" ); document.write( "--------
\n" ); document.write( "This is a contradiction that arose we assumed the x in the equations
\n" ); document.write( "was the same and we assumed the y in the equations was the same.
\n" ); document.write( "----------
\n" ); document.write( "They are not; the system is inconsistent.
