Solve for x by following PEMDAS in reverse to undo what is being done to x
Add 4 to both sides (to undo the subtraction of 4 on the left side)
Multiply both sides by 6 (to undo the division by 6)
So any number larger than 18 will work. This means that the answers are A) 20 and B) 19.
----------------------------------------------
We can check each answer choice by plugging in the x value in question
Checking choice A: Plug in x = 20
True
-------------------
Do the same for choice B. Now plug in x = 19
True
-------------------
So far we've confirmed that A and B are the answers. Let's try choice C
False
----------------------------------------------
Now let's try choice D. Plug in x = 17
False
So that wraps up the check portion.
----------------------------------------------
----------------------------------------------
Once again, the final answers are choice A and choice B.
