Start by moving like terms onto workable sides:

-4+3 = 7/4a + 1/4a

Then simplify a bit:

-1 = 2a (8/4a simplifies into 2a)

Now divide both sides by 2:

-1/2 = a

Answer:

a = -1/2

Step-by-step explanation:

-1/4a - 4 = 7/4a - 3

-1/4a - 7/4a = -3 + 4

-2a = 1

a = 1/-2

a = -1/2

Hope it helps!
