Step-by-step explanation:

Step 1: Define equation

-2x + 14 = 20

Step 2: Solve for x

Subtract 14 on both sides:                    -2x = 6Divide -2 on both sides:                        x = -3

Step 3: Check

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

Substitute in x:                    -2(-3) + 14 = 20Multiply:                               6 + 14 = 20Add:                                     20 = 20

Here we see that 20 does indeed equal 20.

∴ x = -3 is a solution of the equation.
