Math Problem Statement
Solution
Let's work through the system of equations presented in your image by eliminating the fractions.
The system of equations is:
Step 1: Eliminate fractions in the first equation
The least common denominator (LCD) for , , and is . Multiply every term in the first equation by 6:
This simplifies to:
Step 2: Eliminate fractions in the second equation
The least common denominator for , , and is . Multiply every term in the second equation by 12:
This simplifies to:
Step 3: Solve the system of equations
We now have the system of equations:
Let's solve this system using substitution or elimination. I'll use the elimination method.
Multiply the second equation by 5 to align the terms with the first equation:
Now subtract the first equation from this result:
Simplifying:
Step 4: Substitute into one of the original equations
Substitute into :
Final Answer:
The solution to the system is and . The ordered pair is .
So, the correct choice is A: The solution is .
