5y=7x+22
\n" ); document.write( "x=-6y+17\r
\n" ); document.write( "\n" ); document.write( "Re write the equations\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-7 x + 5 y = 22 .............1
\n" ); document.write( "1 x + 6 y = 17 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -6
\n" ); document.write( "Multiply (2) by 5
\n" ); document.write( "42 x -30 y = -132
\n" ); document.write( "5 x + 30 y = 85
\n" ); document.write( "Add the two equations
\n" ); document.write( "47 x = -47
\n" ); document.write( "/ 47
\n" ); document.write( "x = -1
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "-7 x + 5 y = 22
\n" ); document.write( "7 + 5 y = 22
\n" ); document.write( " 5 y = 22 -7
\n" ); document.write( " 5 y = 15
\n" ); document.write( " y = 3
\n" ); document.write( " \n" ); document.write( "
\n" );
