Solve the system by the elimination method.
\n" ); document.write( " 5x-y=-14+2x+y
\n" ); document.write( " 7x+9y+4=3x+8y\r
\n" ); document.write( "\n" ); document.write( "solve eq.1
\n" ); document.write( "eq.1 5x-y=-14+2x+y \r
\n" ); document.write( "\n" ); document.write( "first combine the similar terms
\n" ); document.write( " 5x-2x-y+y=-14
\n" ); document.write( "then proceed to cancellation of like terms:
\n" ); document.write( " 5x-2x-y+y=-14
\n" ); document.write( " 3x =-14\r
\n" ); document.write( "\n" ); document.write( "solve eq.2
\n" ); document.write( "eq.2 7x+9y+4=3x+8y\r
\n" ); document.write( "\n" ); document.write( "first combine the similar terms:
\n" ); document.write( " 7x-3x+9y-8y=-4
\n" ); document.write( "then proceed to cancellation of like terms:
\n" ); document.write( " 4x+y=-4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "combine the answer in eq.1 and 2\r
\n" ); document.write( "\n" ); document.write( "by elimination method we have:
\n" ); document.write( " 3x =-14 (minus) 4x+y=-4\r
\n" ); document.write( "\n" ); document.write( "the answer is: -x+y=-10
\n" ); document.write( "multiplying both side by -1 we have
\n" ); document.write( " -1(-x+y=-10)-1\r
\n" ); document.write( "\n" ); document.write( "final answer: x-y=10
\n" ); document.write( "
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
