Question

What is he answer to this question??????? -15s + 12.81 = 15.71 − 13.5s + 17.2

Answer 1

Okay, so first we will need to combine like terms.

The like terms in the question are -15s and 13.5s.

Combining usually means addition. So you add -15s and 13.5s.

That would be -1.5s.

Now we need to combine the rest of the equation, and that would be 12.81 + 15.71 + 17.2

The answer to that would be 45.72

Now combine the two answers

-1.5s = 45.72

The next step is to divide each term by -1.5

-1.5 ÷ -1.5s would just leave us with s.

Now,

-1.5 ÷ 45.72 will be -30.48.

So you're answer is  s = -30.48

Hope this helped! :D
