Answer:
its b because when subtract 30-24=6
A) y = 2x -4
B) x + 2y = 12
A) -2x + y = -4 then multiplying Equation B by 2
B) 2x + 4y = 24
Adding the equations
5y = 20
y = 4
x = 4
Okay, that was solved by elimination.
If these equations were graphed, they would be two lines that would meet at the point (4, 4)
