An easy common denominator is 60 bc 15*4=60 and everything else can equal 60 too so:
6/60+ 15/60+ 12/60+ 8/60 = 41/60 (you only add the numerator numbers) usually you would reduce the end result too but 41 is a prime number so you cant
Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.
Let's substitute b-2 into the first equation wherever there is an a.
a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3
Now let's find a by substituting -3 into either of the equations to find the value of a.
a = b - 2
a = -3 - 2
a = -5
So your solution set is (-5, -3)
