I'm assuming you need to solve for x and y.
In order to solve for two unknowns, you require two equations. In this case, you use parallel line theorems (Z-pattern in this case) to set up your two equations.
Because <FDC = 136*, you can also say that the exterior angle at C along ray CE is equal to 136*
And since this exterior angle and <DCE are supplementary, they equal 180*, giving your first equation.
136* + 2x + 2y = 180*
x + y = 22*
Because <ACE = 58*, you can also say that the exterior angle at A along ray AB is equal to 58*
And since this exterior angle and <CAB are supplementary, they equal 180*, giving your second equation.
58* + 4x + 6y = 180*
2x + 3y = 61*
Can you take it from here?
