What is 7 +2 = x-4/2​
madam [21]

Answer:

The answer is 11.

Step-by-step explanation:

We will use PEMDAS in this situation.

 7 + 2 = x - 4 / 2

 7 + 2 = x - 2             [divide first

 9 = x - 2                   [add the 7 and 2]

+2       +2                   [the 2 cancels out]

 11 = x

Your answer is 11.

I hope this helped!
