1 answer

To solve for x in the equation 3x - 4 = 8, you can follow these steps:

1. Add 4 to both sides of the equation:
3x - 4 + 4 = 8 + 4
This simplifies to:
3x = 12

2. Divide both sides of the equation by 3 to isolate x:
(3x)/3 = 12/3
This simplifies to:
x = 4

Therefore, the solution to the equation 3x - 4 = 8 is x = 4.
