What is the value of x in the equation 4(x - 1) = 12?

What is the value of x in the equation 4(x - 1) = 12?

Step 1: Start with the equation 4(x - 1) = 12.
Step 2: Divide both sides of the equation by 4 to simplify it. This gives you (x - 1) = 12 / 4.
Step 3: Calculate 12 divided by 4, which equals 3. Now the equation is x - 1 = 3.
Step 4: To find x, add 1 to both sides of the equation. This gives you x = 3 + 1.
Step 5: Calculate 3 + 1, which equals 4. So, x = 4.
