use the elimination method to solve the following system of equations. Provide the solution to the system.
\n" ); document.write( "2x - 5y = -12
\n" ); document.write( "3x - 4y = 3
\n" ); document.write( "=======
\n" ); document.write( "To eliminate the \"x\" terms multiply the top equation by 3 and the
\n" ); document.write( "bottom equation by 2:
\n" ); document.write( "------
\n" ); document.write( "6x - 15y = -36
\n" ); document.write( "6x - 8y = 6
\n" ); document.write( "--------
\n" ); document.write( "Subtract the top from the bottom and solve for \"y\";
\n" ); document.write( "7y = 30
\n" ); document.write( "Divide both sides by 7:
\n" ); document.write( "y = 30/7
\n" ); document.write( "--------------------
\n" ); document.write( "Going back to the original equations to solve for \"x\":
\n" ); document.write( "2x - 5y = -12
\n" ); document.write( "3x - 4y = 3\r
\n" ); document.write( "\n" ); document.write( "Multiply thru the top equation by 4 and the bottom by 5:
\n" ); document.write( "8x - 20y = -48
\n" ); document.write( "15x - 20y = 15
\n" ); document.write( "---------------
\n" ); document.write( "Subtract the top equation from the bottom:
\n" ); document.write( "7x = 63
\n" ); document.write( "x = 9
\n" ); document.write( "-----------
