You can put this solution on YOUR website!
you aren't trying to eliminate numbers but letters.
\n" ); document.write( "for example
\n" ); document.write( "with the linear equations (they make a line on if you graph it)
\n" ); document.write( "x-y=7
\n" ); document.write( "2x+y=8
\n" ); document.write( "if you add the two equations y will be gone because we have a minus y and a plus y\r
\n" ); document.write( "\n" ); document.write( "with the equations
\n" ); document.write( "8x+y=23
\n" ); document.write( "3x+y=10
\n" ); document.write( "if we subtract one from the other we eliminate the y's because y-y =0
\n" ); document.write( "so you need to multiply your equations by a number such that you can subtract or add then and get rid of one of the letters
\n" ); document.write( "try multiplying the first one by 2 and the second one by 3
\n" ); document.write( "that way you'll have 6x in both and can subtract them.
\n" ); document.write( "then you solve for y
\n" ); document.write( "and then when you have y can plug y into any of the equations and solve for x
