7x+9y=26
\n" ); document.write( "x=32-6y
\n" ); document.write( "Solve for y and x\r
\n" ); document.write( "\n" ); document.write( " we have to find the values of x&y so we will use ellimination method\r
\n" ); document.write( "\n" ); document.write( " 7x+9y = 26......(1)\r
\n" ); document.write( "\n" ); document.write( " x+6y = 32.......(2) {got by transfering 6y to left hand side}\r
\n" ); document.write( "\n" ); document.write( " multiply (2) by 7 and subtract (1) & (3) hence (2) becomes 7x+42y= 224..(3)\r
\n" ); document.write( "\n" ); document.write( " subtracting 1& 3 we get -33y = -198 or y = -198/-33 = 6\r
\n" ); document.write( "\n" ); document.write( " substitute for y in (2) we get x = 32- 6(6) = 32-36 = -4\r
\n" ); document.write( "\n" ); document.write( " therefore the values of x& y are x = -4 and y = 6\r
\n" ); document.write( "\n" ); document.write( "
