how do you solve a problem like this: 3m=(-84)
Notice that this means 3 times a number = -84.
To isolate the m we need to do the opposite of 3 times on both sides of the equation. We divide both sides of the equation byt 3.
3m%2F3=-84%2F3
1m=-28
highlight%28m=-28%29
:
Sanity Check, do both sides of the = sign equal when m=-28?
3(-28)=-84
-84=-84 We're right.
Happy Calculating!!!
