Final answer:
The approximate solution to the equation 4inx-8=12 is x=5 inches.
Step-by-step explanation:
To solve the equation 4inx-8=12, we need to isolate the variable x. Firstly, we need to add 8 to both sides of the equation to move the constant term -8 to the right side, resulting in 4inx = 20.
Next, we can divide both sides of the equation by 4in to solve for x. This gives us the approximate solution x = 5 inches.
