5x-y=-18
\n" ); document.write( "4x+2y=92
\n" ); document.write( "These are both the same problem.
\n" ); document.write( "---------------------
\n" ); document.write( "I think it's one problem, and you want to solve for x and y.
\n" ); document.write( "There are 2 equations and 2 unknowns, so it might work out.
\n" ); document.write( "One method it elimination. Multiply one of the eqns by something to get the same coefficients for one of the unknowns.
\n" ); document.write( "If the 1st eqn is multiplied by 2, it will have -2y in it, and the 2nd eqn has 2y also.
\n" ); document.write( "5x-y=-18 --> 10x - 2y = -36
\n" ); document.write( "10x - 2y = -36
\n" ); document.write( "4x + 2y = 92 Then add the 2 eqns
\n" ); document.write( "--------------
\n" ); document.write( "14x + 0y = 56
\n" ); document.write( "x = 4 xxxxxxxxxxxxxxxxxx That's one
\n" ); document.write( "-------------
\n" ); document.write( "Then sub 4 for x into an eqn to find y
\n" ); document.write( "4x+2y=92
\n" ); document.write( "16+2y=92
\n" ); document.write( "2y = 76
\n" ); document.write( "y = 38 yyyyyyyyyyyyyyyyyyy
\n" ); document.write( "That's it. \n" ); document.write( "
\n" );
