You can put this solution on YOUR website!
Try to solve it and see
\n" ); document.write( ":
\n" ); document.write( "2x - 4y = 5
\n" ); document.write( "3x + 2y = 6
\n" ); document.write( "multiply the 2nd equation by 2 and add to the 1st solution
\n" ); document.write( "2x - 4y = 5
\n" ); document.write( "6x + 4y = 12
\n" ); document.write( "----------------Addition eliminates y, find x
\n" ); document.write( "8x = 17
\n" ); document.write( "x = 17/8
\n" ); document.write( "x = 2.125
\n" ); document.write( "use the 2nd original equation to find y, replace x with 2.125
\n" ); document.write( "3(2.125) + 2y = 6
\n" ); document.write( "6.375 + 2y = 6
\n" ); document.write( "2y = 6 - 6.375
\n" ); document.write( "2y = -.375
\n" ); document.write( "2y = -.375/2
\n" ); document.write( "y = -.1875
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Confirm our solutions of x=2.125 and y=-.1875 using the 1st equation
\n" ); document.write( "2(2.125) - 4(-.1875) =
\n" ); document.write( "4.25 + .75 = 5
\n" ); document.write( ":'
\n" ); document.write( "We can say this system of equations has only one solution \n" ); document.write( "
