Final Answer: The solution to the system of equations is \(\boxed{x = 1, y = -4}\)

Steps

Step 1 :The system of equations is given as: \[\left\{\begin{array}{l} -6 x+4 y=-22 \\ -7 x+y=-11 \end{array}\right.\]

Step 2 :First, we solve the second equation for y: \[y = 7x - 11\]

Step 3 :Then, we substitute this into the first equation to solve for x: \[-6x + 4(7x - 11) = -22\] which simplifies to \[22x - 44 = -22\]

Step 4 :Solving this equation gives us the value of x: \[x = 1\]

Step 5 :Substituting x = 1 back into the second equation, we can solve for y: \[-7(1) + y = -11\] which simplifies to \[y = -4\]

Step 6 :Final Answer: The solution to the system of equations is \(\boxed{x = 1, y = -4}\)
