Once again, two angles are supplements when they add up to 180.
This time we will have two equations.
Equation 1:
Equation 2:
-----------------------------
Plug (60 + 3B) into equation 1 for A
Equation 1:
Combine like terms
Subtract 60 from both sides
Divide both sides by 4
Now plug 30 into equation 2 for B
Equation 2:
Simplify
