Step-by-step explanation:

Step 1: Define equation

-5 + 22 = r - 4 + 3r + 5

Step 2: Solve for r

Combine like terms:                    17 = 4r + 1Subtract 1 on both sides:             16 = 4rDivide 4 on both sides:               4 = rRewrite:                                        r = 4

Step 3: Check

Plug in r to verify it's a solution.

Substitute:                    -5 + 22 = 4 - 4 + 3(4) + 5Add/Subtract:               17 = 3(4) + 5Multiply:                        17 = 12 + 5Add:                              17 = 17
