You can put this solution on YOUR website!
3 x -4 y = -10 .............1
\n" ); document.write( "
\n" ); document.write( "2 x + 5 y = 70 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 5
\n" ); document.write( "Multiply (2) by 4
\n" ); document.write( "15 x -20 y = -50
\n" ); document.write( "6 x + 20 y = 280
\n" ); document.write( "Add the two equations
\n" ); document.write( "21 x = 230
\n" ); document.write( "/ 21
\n" ); document.write( "x = 11
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3 x -4 y = -10
\n" ); document.write( "33 -4 y = -10
\n" ); document.write( " -4 y = -10 -33
\n" ); document.write( " -4 y = -43
\n" ); document.write( " y = 11
\n" ); document.write( "x= 11
\n" ); document.write( "y= 11
