Question

Complete the following statement.a0

Answer 1

x = 10

Step-by-step explanation

We want to find the missing box in the statement given.

Let the box be represented by x:

`x\text{ + (-7) = 3}`

To solve this, move (-7) to the other side, the sign changes:

`\begin{gathered} x\text{ = 3 + (+7)} \\ x\text{ = 3 + 7} \\ x\text{ = 10} \end{gathered}`

The box is 10.
