Question

What makes 3 plus 7 plus 2 = plus 2 true

Answer 1

10

Explanation:

3 plus 7 equals 10

Answer 2

We have the following:

`3+7+2=x+2`

Now, for this to be true we must look for a number that makes the sum of both sides equal, as follows

`\begin{gathered} 3+7+2=x+2 \\ x=3+7 \\ x=10 \\ \text{then} \\ 3+7+2=10+2 \\ 12=12 \end{gathered}`

Therefore, the number that makes the equality true is 10
