Step-by-step explanation:

Step 1: Define

6(x - 1) = 9(x - 4)

Step 2: Solve for x

Distribute:                                   6x - 6 = 9x - 36Subtract 6x on both sides:        -6 = 3x - 36Isolate x term:                             30 = 3xIsolate x:                                      10 = xRewrite:                                       x = 10

Step 3: Check

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

Substitute in x:                    6(10 - 1) = 9(10 - 4)Subtract:                              6(9) = 9(6)

Here we see that the 2 expressions are exactly the same.

∴ x = 10 is the solution to the equation.
