So,

1/4(3c + 5) + -1/2(2c + 3) = 1/2

First, we distribute to get rid of the parentheses. (PEMDAS)
3/4c + 1 1/4 - c - 1 1/2 = 1/2

Now, we collect like terms.
-1/4c - 1/4 = 1/2

Add 1/4 to both sides.
-1/4c = 3/4

Now, multiply by the reciprocal (-4/1).
c = -3

Check your answer.

1/4(3[-3] + 5) + -1/2(2[-3] + 3) = 1/2

1/4(-9 + 5) + -1/2(-6 + 3) = 1/2

-2 1/4 + 1 1/4 + 3 - 1 1/2 = 1/2

-1 + 1 1/12 = 1/2

1/2 = 1/2
