Explanation:
Step 1: Define
5(x - 1) = 23
Step 2: Solve for x
- Divide 5 on both sides: x - 1 = 23/5
- Add 1 to both sides: x = 28/5
Step 3: Check
Plug in x into the original equation to verify it's a solution.
- Substitute in x: 5(28/5 - 1) = 23
- (Parenthesis) Subtract: 5(23/5) = 23
- Multiply: 23 = 23
Here we see that 23 does indeed equal 23.
∴ x = 28/5 is the solution to the equation.
