Answer: 28/5    or 5.6

Step-by-step explanation:

5(x-1) = 23        Distribute on the left side

5x - 5 = 23        Add 5 to both sides

    +5      +5

5x = 28       Divide both sides by 5

x = 28/5

Step-by-step explanation:

Step 1: Define

5(x - 1) = 23

Step 2: Solve for x

  1. Divide 5 on both sides:                    x - 1 = 23/5
  2. Add 1 to both sides:                          x = 28/5

Step 3: Check

Plug in x into the original equation to verify it's a solution.

  1. Substitute in x:                     5(28/5 - 1) = 23
  2. (Parenthesis) Subtract:        5(23/5) = 23
  3. Multiply:                                23 = 23

Here we see that 23 does indeed equal 23.

∴ x = 28/5 is the solution to the equation.
