Wo equations are given below: a − 3b = 9 a = b − 3 what is the solution to the set of equations in the form (a, b)? (−9, −6) (−4, −3) (−6, −3) (−9, −7)

A - 3b = 9
a = b - 3

With our set of equations, we should substitute our variables with their values, and whichever answer equals (or cancels) out is the correct one.

(-9, -6);
-9 - 3(-6) = 9
-9 + 18 = 9
18 = 18
This is correct so far.

(-9, -6);
-9 = -6 - 3
-9 = -9
This is also correct!

From the work above, we can conclude that the set of equations (-9, -6) is the correct answer.

I hope this helps!
