Hey i’m struggling with number 13 so show your work. thx

Step-by-step explanation:

Because is being multiplied by S, we can divide from both sides of the equation. This will give us:

÷

But, that looks a bit hectic. Instead of dividing, you can multiply by the reciprocal (which is essentially how to divide fractions). So, instead of ÷, you get:

×

When multiplying fractions, remember you can just multiply straight across-- numerator x numerator, then denominator x denominator.

By doing that, you get the fraction

cannot be simplified any more, so S= is your answer :)

I hope this helps
