-5 x -10 y = -22 .............1
\n" ); document.write( "Total value
\n" ); document.write( "10 x + 15 y = 35 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 3
\n" ); document.write( "Multiply (2) by 2
\n" ); document.write( "-15 x -30 y = -66
\n" ); document.write( "20 x + 30 y = 70
\n" ); document.write( "Add the two equations
\n" ); document.write( "5 x = 4
\n" ); document.write( "/ 5
\n" ); document.write( "x = 1
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "-5 x -10 y = -22
\n" ); document.write( "-4 -10 y = -22
\n" ); document.write( " -10 y = -22 + 4
\n" ); document.write( " -10 y = -18
\n" ); document.write( " y = 2
\n" ); document.write( "x= 1
\n" ); document.write( "y= 2
