The given equation is


|26-4c|=-2

Remember that an absolute value equation is rewritten as two other equations


\begin{gathered} 26-4c=-2 \\ 26-4c=-(-2) \end{gathered}

Let's solve both equations


26-4c=-2\rightarrow-4c=-2-26\rightarrow-4c=-28\rightarrow c=(-28)/(-4)=7
26-4c=-(-2)\rightarrow26-4c=2\rightarrow-4c=2-26\rightarrow c=(-24)/(-4)=6

Therefore, the solutions are 7 and 6.
