If you would like to know what is the solution to the set of equations in the form (a, b), you can calculate this using the following steps:

a − 3b = 4
a = b − 2
_______________
a − 3b = 4
b - 2 - 3b = 4
- 2b = 6
b = - 3

a = b − 2 = - 3 - 2 = - 5

(a, b) = (-5, -3)

The correct result would be (-5, -3).
