Final Answer: \[\boxed{\begin{array}{l} 8x + 10y = -110 \ 4x + 8y = -76 \end{array}}\]

Steps

Step 1 :The given system of equations is: \[\begin{array}{l} 4x + 5y = -55 \ 2x + 4y = -38 \end{array}\]

Step 2 :We are asked to find a system of equations that has the same solution as the given system. To do this, we can multiply each equation in the given system by a non-zero constant. This will not change the solution of the system.

Step 3 :Let's multiply the first equation by 2 and the second equation by 2. This gives us the new system of equations: \[\begin{array}{l} 8x + 10y = -110 \ 4x + 8y = -76 \end{array}\]

Step 4 :This new system of equations has the same solution as the original system. Therefore, the system of equations that has the same solution as the given system is: \[\begin{array}{l} 8x + 10y = -110 \ 4x + 8y = -76 \end{array}\]

Step 5 :Final Answer: \[\boxed{\begin{array}{l} 8x + 10y = -110 \ 4x + 8y = -76 \end{array}}\]
