Start with the given expression.

Set the denominator equal to zero.

Remember, dividing by 0 is undefined. So if we find values of "t" that make the denominator zero, then we must restrict those values.

Add 7 to both sides

Combine like terms on the right side

Divide both sides by 3 to isolate t

So this means that makes the denominator equal to zero.

So we MUST make the restriction to avoid dividing by zero (since makes the denominator equal to zero).
