Question

3 + ? = 10

Sandra guessed the number 5 for the solution to the equation below. Does Sandra have the correct solution?

3 + ? = 10

Yes. 5 is the correct solution.

No. 5 is not the correct solution.

Answer 1

To solve the equation \(3 + ? = 10\), we need to determine what number added to 3 gives us 10.

Subtracting 3 from both sides of the equation:

\[ ? = 10 - 3 \] \[ ? = 7 \]

Since Sandra guessed 5, which is not equal to 7, she does not have the correct solution.

So the answer is:

No. 5 is not the correct solution.
