Solve each system by substitution. Determine whether the
\n" ); document.write( "equations are independent, dependent, or inconsistent.
\n" ); document.write( "2x – y = 4
\n" ); document.write( "2x – y = 3
\n" ); document.write( "---
\n" ); document.write( "Subtract the left side from the right side to get:
\n" ); document.write( "0 = 1
\n" ); document.write( "---
\n" ); document.write( "That is a contradiction resulting from our assuption
\n" ); document.write( "that the variables have the same value in the two
\n" ); document.write( "equations.
\n" ); document.write( "---
\n" ); document.write( "They don't.
\n" ); document.write( "So we say the system is inconsistent.
\n" ); document.write( "---
\n" ); document.write( "It has no solution.
