    Whatever you do to one side you must do it to the other.

    So, starting with ....

    3 - 5n = - 22

    Subtract 3 from both sides

    3 - 3 - 5n = - 22 - 3

    - 5n = - 25

    Divide both sides by 5

    - 5n/5 = - 25/5

    - n = - 5

    and because both sides are negative you can make them both positive.

    n = 5

    This is basic algebra.

    3 - 5n = -22

    -5n = -22 - 3

    -5n = -25 (you can cut out the negative sign as it is present on both sides)

    5n = 25

    n = 25/5

    n = 5

    3 + 22 = 5n

    25 = 5n

    25/5 = n

    n = 5

    The essential property is that whatever you do to one side 

    of an equation you must do to the other.

    Bring like terms to each side of the equation. 

    Subtracting 3 from each side makes 5n equal to minus 25. 

    To find n, divide both sides by minus 5 

    and you will see that n is equal to five.

    Using the associative property of addition we take 3 out from -22 to get

    3 + (-25)

    Next using the associative property of multiplication we take the factor of 5 from -25

    3 + (-5 * 5)

    Then we simply

    3 - (5 * 5)

    3 - 5(5)

    So now the formula looks like the LHS of the equation and therefore: n = 5

    If: 3 -5n = -22

    Subtract 3 from both side: 3 -3 -5n = -22 -3 or -5n = -25

    Divide both sides by - 5: n = 5

    Check: 3 -(5*5) = -22

    Remember: a minus divided by a minus equals a plus

    Take away 3 from both sides, -5n=-25

    Isolate n by dividing both sides by -5, n = -25/-5

    n = 5

    Add to original equation for proof, 3 - (5 x 5) = -22

    Draw a picture of a duck, the teacher will be so distracted she'll try to give it a cracker, so you'll either get an a or a c.
