Hey, \n" ); document.write( "So for this one, we need to work on each side of the equal sign at a time. \n" ); document.write( "For 5y-4+18 \n" ); document.write( "-4+18=14 \n" ); document.write( "So the left side equals: \n" ); document.write( "5y+14 \n" ); document.write( "Now for the right side of the equals sign: \n" ); document.write( "7y+20-4y \n" ); document.write( "7y-4y=3y \n" ); document.write( "So the right side equals: \n" ); document.write( "3y+20 \n" ); document.write( "So the whole equation now equals: \n" ); document.write( "5y+14=3y+20 \n" ); document.write( "If you subtract 3y from both sides, the 3y on the right side is cancelled out: \n" ); document.write( "5y-3y+14=3y-3y+20 => \n" ); document.write( "2y+14=20 \n" ); document.write( "Now we subtract 14 from both sides and the 14 on the left side is cancelled out: \n" ); document.write( "2y+14-14=20-14 => \n" ); document.write( "2y=6 \n" ); document.write( "Now divide both sides by 2: \n" ); document.write( "y=3 \n" ); document.write( "I hope this helps! \n" ); document.write( " |
