Answer:

$\huge\boxed{\bf\:c = \frac{11}{4}}$

Step-by-step explanation:

$4c + 2c = 4c + \frac{11}{2}$

Cancel 4c on both the sides of the equation.

$2c = \frac{11}{2}$

Bring the 2 in the denominator of 11/2 to the left hand side of the equation.

$2*2c = 11\\4c = 11$

Bring 4 to the right hand side if the equation.

$\boxed{\bf\:c = \frac{11}{4}}$
