we have the system of equations
--------> equation 
--------> equation 
Multiply by
equation 
--------> equation 
Adds equation
and equation 

Find the value of y
the solution of the system is the point 
therefore
the answer is

2x - 5 = 7
2x = 7 + 5
2x = 12
2x/2 = 12/2
x = 6
to check:
2x - 5 = 7
2(6) - 5 = 7
12 - 5 = 7
7 = 7
The answer is D becuase 18 plus 6 is twenty four
Answer:
1 is factors of this question
