    Answer:

    a= 4/3

    Step-by-step explanation:

    1.) Simplify both sides of the given equation:

    1/4a + -5/6 = -1/2

    2.) Add the 5/6 to both sides (cancels the -5/6)

    1/4a + -5/6 (+5/6) = -1/2 (+5/6)

    1/4a = 1/3

    3.) Multiply both sides by 4 (the denominator)

    4 * 1/4a = 1/3 * 4

    a = 4/3

    To check the solution, plug in 4/3 into a:

    4/3/4 – 5/6 = -1/2

    2.) Dividing fractions is also multiplication:

    (4/3 * 1/4) – 5/6 = -1/2

    3.) Get the difference of 1/3 and 5/6

    1/3 – 5/6 = -1/2

    4.) Simplify -3/6 (3 goes into 3 ONCE and into 6 TWO times)

    -3/6 = -1/2

    5.) Check to see if both sides match

    -1/2 = -1/2
