You would have to multiply 6 bags of 6 gel pens together so 6x6, divide it by the friends so 6x6=36/9=4
Y = 2x + 50,
It's easier to look at the first set of numbers and then make a formula from there. so we need x to be zero and y to be 50, which is why the formula listed works.
In this exercise we have to use subtraction knowledge to calculate the final value of the equation, like this:
Letter C
