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:
-17x - -43z + 20
Step-by-step explanation:
-17x - -43z + 20
<span>1/12+3/8y=5/12+5/8y
</span><span>3/8y- 5/8 y = 5/12- 1/12
-2/8y = 4/12
-1/4y = 1/3
y = 1/3 *(-4)
y = - 4/3</span>
