Step-by-step explanation:

Step 1: Define

8 = a - 2

Step 2: Solve for a

  1. Add 2 on both sides:                    10 = a
  2. Rewrite:                                          a = 10

Step 3: Check

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

  1. Substitute in a:                    8 = 10 - 2
  2. Subtract:                              8 = 8

Here we see that 8 does indeed equal 8.

∴ a = 10 is the solution to the equation.
a=10


8 = a-2
+2= a +2
a=10
