Honestly, I don’t know this math ;-;

Answer 2

Answer:

m = -4

Step-by-step explanation:

First you have to deal with the right side of the equation since it's not spread out.

You therefore have to distribute (in order)

5×1= 5,

5×-m= -5m

And

-2×1 = -2

-2×-m = 2m

Now set it up in the order it was at first (not necessary, but helpful)

15 = 5-5m-2+2m

Add the common values...

5-2= 3

-5m+2m= -3m

Your equation should now look like this:

15= 3-3m

At this point you need to get the common values on the same side, so you would subtract 3 from both sides

15-3= 12

3-3= 0

Since you the 3 cancelled out on the right side, your equation now looks like this:

12= -3m

(Or -3m= 12)

At this point you only need to get m by itself so you would divide by -3 on both sides

-3m/-3= m (or 1m: m is understood as such)

12/-3= -4

The final answer should be

m = -4
