Hello we are doing substitution and i am having trouble doing it with fractions. i will use this for my fraction sign /. please help.
\n" ); document.write( "x/2+y/3=7/6
\n" ); document.write( "---
\n" ); document.write( "Get rid of the fractions:
\n" ); document.write( "Multiply thru by 6 to get
\n" ); document.write( "3x + 2y = 7
\n" ); document.write( "-----
\n" ); document.write( "x/4-3y/2=9/4
\n" ); document.write( "Multiply thru by 4 to get:
\n" ); document.write( "x - 6y = 9
\n" ); document.write( "--------------------------------
\n" ); document.write( "New system:
\n" ); document.write( "3x+2y=7
\n" ); document.write( "x-6y=9
\n" ); document.write( "--------------------
\n" ); document.write( "Substitute for \"x\" and solve for \"y\":
\n" ); document.write( "3(6y+9)+2y = 7
\n" ); document.write( "18y + 27 + 2y = 7
\n" ); document.write( "20y = -20
\n" ); document.write( "y = -1
\n" ); document.write( "--------------
\n" ); document.write( "Substitute into x = 6y+9 to solve for \"x\":
\n" ); document.write( "x = 6*-1+9
\n" ); document.write( "x = -6+9
\n" ); document.write( "x = 3
\n" ); document.write( "--------------
