The easiest is to multiply all 3 together but since 9is divisible by 3 all wee need is to multiply 2 and 9 to make 18. \n" ); document.write( ". \n" ); document.write( "Now multiply the top and bottom line by 18 \n" ); document.write( "The 2s will cancel out leaving 9x/1 and the 3 will cancel out to be 6y/1 and the 9 will cancel out to be 2y/1. \n" ); document.write( ". \n" ); document.write( "This shows as : \n" ); document.write( " \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Now much easier to see how to solve id go with subtraction so x cancels out and solve for y first. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Plug in y and solve for x \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
