Solve the radical equation. Be sure to check all solutions to eliminate extraneous solutions.
tatyana61 [14]

Answer: \large\boxed{\text{No Solution}}

Step-by-step explanation:

<u>Given equation</u>

\sqrt{t+1}+9=7

<u>Subtract 9 on both sides</u>

\sqrt{t+1}+9-9=7-9

\sqrt{t+1}=-2

<u>Conclusion</u>

\text{Since radical values are always positive, it is false that }\sqrt{t+1}\text{ will equal to -2}

\text{Therefore, it is }{\large\boxed{\text{No Solution}}}\text{ in the context of real numbers}

Hope this helps!! :)
