Question: 1 / 400

What is the solution to the equation 5(x - 1) = 20?

x = 3

x = 4

x = 5

To solve the equation 5(x - 1) = 20, start by isolating the expression inside the parentheses. You can do this by dividing both sides of the equation by 5. This yields:

x - 1 = 20 / 5

Simplifying the right side gives:

x - 1 = 4

Next, to solve for x, add 1 to both sides:

x = 4 + 1

Simplifying this results in:

x = 5

Thus, the solution to the equation is x = 5. This confirms that the correct answer aligns with the mathematical process used in solving for x.
