Answer:
(-11, - 9)
Step-by-step explanation:
Given the 2 equations
a - 3b = 16 → (1)
a = b - 2 → (2)
Substitute a = b - 2 into (1)
b - 2 - 3b = 16
- 2b - 2 = 16 ( add 2 to both sides )
- 2b = 18 ( divide both sides by - 2 )
b = - 9
Substitute b = - 9 into (2) for the corresponding value of a
a = - 9 - 2 = - 11
Solution is (- 11, - 9)
