B.
Because if you replace the x with 6, it becomes 7(6) = 42, or 7 x 6 = 42.

We have a linear equation here.
The question is asking you:
What number times 7 = 42?
The obvious answer is 6, right?
So, x = 6...Choice B
To solve it the algebra way, divide both sides of the equation by 7.
7x = 42
x = 42 divided by 7
x = 6

7x=42
Take 7 and divide it by 7.
Take 42 and divide it by 7.
7 divided by 7 is one or 'X'
42 divided by 7 is 6.
So 'X' equals 6 and the answer is B
