Explain your answer

7.
two equations are given below:

a – 3b = 4
a = b – 2

what is the solution to the set of equations in the form (a, b)? (5 points)

(–2, –2)
(–3, –1)
(–9, –7)
(–5, –3)

D. (-5, -3)

Step-by-step explanation:

Solve the equation by substitution method to get b - 2 - 3b = 4. Then you substitute b into simplest to get, b= -3. Repeat the same process with a to get, a = -5. So your answer would be (-5, -3)

Good luck!!
