Solve using the substitution method, the elimination method, or the graphing method.
\n" ); document.write( "2(x - y) = 3 + x
\n" ); document.write( "x = 3y + 4
\n" ); document.write( "--------------
\n" ); document.write( "2x-2y = 3+x From eqn 1
\n" ); document.write( "Subtract x
\n" ); document.write( "x-2y = 3
\n" ); document.write( "x-3y = 4 Eqn 2
\n" ); document.write( "Subtract to eliminate x
\n" ); document.write( "0x + y = -1
\n" ); document.write( "y = -1
\n" ); document.write( "Sub into eqn 2
\n" ); document.write( "x = 3*(-1) + 4
\n" ); document.write( "x = -3 + 4
\n" ); document.write( "x = 1\r
\n" ); document.write( "
