-44
Пошаговое объяснение:
Let's call the sum "x".
x = (3/4)a + 24
We know that x = -9, so we can substitute that into the equation:
-9 = (3/4)a + 24
Next, we'll isolate "a" by subtracting 24 from both sides:
-33 = (3/4)a
Finally, we'll divide both sides by 3/4 to find the value of "a":
a = -44
So, the value of "a" is -44.
