What is the solution set of the given system?

2x - y - 4 = 0

3x + y - 9 = 0

Choices; { (6/5, 13/5) }

{ (13/5, 6/5) }

{ (5, 6) }

{ (6, 5) }

There are two equations, two unknowns in this problem, hence using the degrees of freedom, this problem can be solved.

2x - y - 4 = 0

3x + y - 9 = 0

5x - 13 = 0

x = 13/5

y = 6/5

The answer is choice B { (13/5, 6/5) }
