Two equations are given below: a – 3b = 9 a = b – 3 What is the solution to the set of equations in the form (a, b)? (5 points) (–9, –6) (–4, –3) (–6, –3) (–9, –7)

OpenStudy (anitas.):

I think it is the second one(-4,-3)

OpenStudy (agl202):

\[\left( b-3 \right)-3b=9\]

OpenStudy (agl202):

Combine like terms starting with b: \[-2b=12\]
