Answer:

15 x 1 + 5 x 3 = 30

Step-by-step explanation:

If you turn the x into a one then it multiplies 15 by one and then it remains at 15, then you multiply 5 and 3 so that's 15 and then 15 + 15 is 30.

Factor −1/2−1/2 out of −1/2x+6.

That's unusual: repetition: -1/2 - 1/2.

Did you perhaps mean "Factor -1/2 out of (-1/2)x + 6?

Let's do that. Let's rewrite 6 as (-1/2)(-12).

Then (-1/2)x + 6 (-1/2)x -(1/2)(-12)
-------------- = ------------------------ = x - 1/2
-1/2 -1/2

Hope that's what you wanted. If not, please try to apply a similar approach to solving this particular problem.
