    uh, not quite, you want to subtract 4.95 from each side... left side: 4.95+.35x right side: 6.7 4.95+.35x - 4.95 = 6.7 - 4.95 keep going from here

    not quite, remember that you can't combine variables and numbers... 4.95 - 4.95 = ?

    4.95 - 4.95 = 0 4.95 + 0.35x - 4.95 = 0.35x, understood? we subtract 4.95 - 4.95 and leave 0.35x alone since it's got the letter x attached to it
