svlad2 [7]

Answer: Option B

Step-by-step explanation:

If the solution is 6 then it means that x=6.

Let's call the missing number <em>y</em>

<em> </em>Substitute x=6 and <em>y</em> into the equation and solve for <em>y: </em>

6(6+4)=6(6+7)-y\\6(10)=6(13)-y\\60=78-y\\y=78-60\\y=18

The options does not show 18, but the option B shows 3x, then if x=6:

3x=3*6=18

The answer is the option B
