Rewrite the equation for x, and express its value in terms of a.
3/a x-4=20

x=8a

Step-by-step explanation:

3/a x-4=20

We need to solve for x

Add 4 to each side

3/a x-4+4=20+4

3/a x = 24

Multiply each side by a/3 so we can get x alone

a/3 *3/a x = 24 * a/3

x = 8a

x=8a

Step-by-step explanation:

We have to solve for x.

Add 4 to each side

Multiply each side by a/3 so we can get x
