7m+3(m+2)=-24
Distribute
3(m+2)=3m+6
7m+3m+6=-24
Combine like terms
7m+3m=10m
10m+6=24
Do the additive inverse of addition
-24-6=
Do keep change change
-24+-6=-30
10m=-30
Do the inverse of division/multiplication
the m cancels out
-30÷10=-3
because a negative divided by a positive equals a negative the result is -3
this is why it is -3.

Alternate angles are defined as angles that are located in opposite positions when we look at them relative to a transverse line that intersects two horizontal lines.

Now, we want to find the alternate angle to angle RUN.

The same transverse line cuts the other horizontal line PQ at point O.

Therefore the alternate angle to angle RUN is angle POU
