Answer:
x=-15 and x=21
Explanation:
Solve the given absolute value equation for the variable "x."

Start by getting the absolute value by itself:

Subtract "4" from either side of the equation.

Multiply each side of the equation by "3."

The right-hand side of the equation is not a negative number. So we can solve for both the left and right distances.
Starting with the left distance:

Add the value of "3" to both sides of the equation.

Now the right distance:

Add the value of "3" to both sides of the equation.

Thus, x=-15 and x=21.
