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

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
