    A = 40

    Step-by-step explanation:

    Step 1: Simplify both sides of the equation.

    3/4 (2a-6) + 1/2=2/5 (3a+20)

    (3/4) (2a) + (3/4) (-6) + 1/2 = (3a) + (2/5) (20)

    (distribute)

    3/2a + - 9/2 + 1/2 = 6/5a + 8

    (3/2 a) + (-9/2 + 1/2) = 6/5a + 8 (Combine like terms)

    3/2a + - 4 = 6/5a + 8

    3/2a - 4 = 6/5a+8

    Step 2: Subtract 6/5a from both sides.

    3/2a - 4 - 6/5 a = 6/5a + 8 - 6/5 a

    3/10 a - 4 = 8

    Step 3: Add 4 to both sides.

    3/10a - 4 + 4 = 8 + 4

    3/10 a = 12

    Step 4: Multiply both sides by 10/3

    (10/3) * (3/10a) = (10/3) * (12)

    a = 40
