For this case, we must clear variable "x" from the given equation, expressed in terms of "a".

We have:

[tex]\frac {3} {a} x-4 = 20[/tex]

By clearing "x" we have:

Adding 4 to both sides of the equation:

[tex]\frac {3} {a} x = 20 + 4[/tex]

Multiplying by[tex]\frac {a} {3}[/tex] on both sides of the equation:

[tex]x = \frac {24a} {3}\\x = 8a[/tex]

So,[tex]x = 8a[/tex]

Answer:

[tex]x = 8a[/tex]
