Step-by-step explanation:

Step 1: Define

3x + 1 = 10

Step 2: Solve for x

  1. Subtract 1 on both sides:                    3x = 9
  2. Divide 3 on both sides:                       x = 3

Step 3: Check

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

  1. Substitute in x:                    3(3) + 1 = 10
  2. Multiply:                               9 + 1 = 10
  3. Add:                                     10 = 10

Here we see that 10 does indeed equal 10.

∴ x = 3 is the solution to the equation.
