I am having trouble with the following problem. I truly need help.
\n" ); document.write( "9x + 24y = 90
\n" ); document.write( "3x + 8y = 30
\n" ); document.write( "These need to be solved using the multiplication/addition method. I have several more problems like this and will use this as an example. I need step by step directions so I can do the other problems. Thank-you so, so much!!!
\n" ); document.write( "-------------------
\n" ); document.write( "That's the elimination method - you eliminate the variables by multiplying to get the same coefficient for one of them.
\n" ); document.write( "------------
\n" ); document.write( "For this example, tho, eqn 1 is 3 times eqn 2. No single solution is possible.
\n" ); document.write( "If you graph these 2, you get the same line twice.
