Math Problem Statement
Which system of equations has the same solution as the system below?
4x + 4y = -44
2x + 2y = -22
Solution
Let's analyze the question and solve it.
The given system of equations is:
Step 1: Simplify the equations if possible
The second equation, , can be rewritten by dividing through by 2:
For the first equation, , divide through by 4:
Thus, both equations reduce to , meaning they are equivalent.
Step 2: Check which system has the same solution
To determine which option has the same solution as the original system, let’s verify the given choices.
-
Option 1: Solve these equations:
- First equation: simplifies to .
- Second equation does not match this simplification.
Not correct.
-
Option 2: Adding these equations eliminates and does not match.
