• Order of Operations: BPEMDAS
• Equality Properties

Explanation:

Step 1: Define equation

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

Step 2: Solve for r

1. Combine like terms: 17 = 4r + 1
2. Subtract 1 on both sides: 16 = 4r
3. Divide 4 on both sides: 4 = r
4. Rewrite: r = 4

Step 3: Check

Plug in r to verify it's a solution.

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