Question:
What is the common denominator of 
in the complex fraction 
A) 
B) 
C) 
D) 
Answer:
Option D : 3 is the common denominator
Explanation:
It is given that the complex fraction
We need to determine the common denominator of from the complex fraction.
Let us consider the fraction
To find the common denominator, let us take LCM.
Thus, rewriting the above fraction as,
The LCM can be determined by multiplying the denominators.
Thus, we get,
Thus, the common denominator is 3.
Hence, Option D is the correct answer.
Answer:
y = -10x + 6
Step-by-step explanation:
Answer:
No solution
Step-by-step explanation:
Note how "2x" shows up in both equations. This suggests doing a substitution to solve the system.
Focus first on the first equation. Solving 2x - y = 7 for 2x, we get:
2x = y + 7.
Next, we substitute y + 7 for 2x in the second equation:
y = (y + 7) + 3.
Simplifying this produces:
0 = 10
This is not true and can never be true. Thus, this system has no solution.
