Answer 2

Step-by-step explanation:

First let's say the x is a variable and not a product

We put brackets to make the order of operations more obvious :

7+7/7+7x7–7 becomes 7+(7/7)+(7x7)−7

Then let's put the product symbol where it belongs :

7+(7/7)+(7×x×7)−7

We now do the operations inside the brackets :

7+1+49x−7

The two sevens cancel each other out so we get:

49x+1

Then if we consider the x as a product following the same procedure we get :

7+(7/7)+(7×7)−7

7+1+49–7

49+1=50

But as we don't know if the x is a product or a variable we should be extra careful so let's say that x=1 so that both of the possibilities give us the same result and voilà
