Answer 2

Option C is correct.

subtraction property of equality

Explanation:

As per the given information:

Daniela's work to solve the equation:
`13x+42 = 276`

Subtract 42 from both sides we get;

`13x = 234`

Divide both sides by 13 we have;

`x =18`

She added the number 42 instead of subtracting both the sides.

therefore, subtraction property of equality does Daniela need to use to avoid her error
