Natalia solved the problem below incorrectly. Find Natalia's mistake, explain what she should have done and tell me what the correct answer is.

x:5 + 2 = 7

x:5 + 2 + - 2 = 7 + 2

x:5 = 9

x:5x5 = 9x5

x = 45

She made the mistake in step 2.

Step-by-step explanation:

Natalia's mistake is that she added 2 to the 7 when she should have subtracted it.

x:5 + 2 = 7

x:5 + 2 - 2 = 7 - 2

x:5 = 5

Then multiply both sided by 5 to get rid of the division on the left

x = 25

This gives us the answer to x.
