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)

Answer:
0.89 g/cm³
Step-by-step explanation:
used the formula d=M/V
M is mass which is = 80g
V is volume which is = 90cm³
d = 80/90
d = 0.89 g/cm³
