Answer 3

To solve the equation, you need to isolate the variable z. Let's break down the equation and solve it step-by-step:

The equation is: (3z - 15.8) • 4 = 14.8

Step 1: Distribute the 4 on the left side of the equation. 4 * 3z - 4 * 15.8 = 14.8

Step 2: Simplify both sides of the equation. 12z - 63.2 = 14.8

Step 3: Move the constant term to the right side of the equation by adding 63.2 to both sides. 12z = 14.8 + 63.2

Step 4: Simplify the right side. 12z = 78

Step 5: Finally, solve for z by dividing both sides by 12. z = 78 / 12 z = 6.5

The solution to the equation is z = 6.5.
