Step-by-step explanation:
The answer to your question is <-8 :)
<u>PEMDAS</u>
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction.
First, divide 3 from both sides of the equation:


Next, isolate the variable, x, by rooting both sides of the equation:

x = ±4
C) ±4 is your answer.

15 is the answer, I think.
There are three variables, so it really doesn't make sense. But, if you don't solve for s, and make it stay how it is, then the intersect would be (0, -2s)
