You can put this solution on YOUR website!
x=2-4y
\n" ); document.write( "3(2-4y)+2y=11
\n" ); document.write( "6-12y+2y=11
\n" ); document.write( "6-14y=11 ___ OOPS!! ___ 6 - 10y = 11
\n" ); document.write( "-14y=5 ________________ -10y = 5
\n" ); document.write( "-14y/-14 =y ___________ y = -1/2
\n" ); document.write( "5/-14= ?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ x = 2 - 4(-1/2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 4
\n" ); document.write( " \n" ); document.write( "
