Explanation:
Step 1: Define Equation
72 = 5x + 22
Step 2: Solve for x
- Subtract 22 on both sides: 50 = 5x
- Divide 5 on both sides: 10 = x
- Rewrite: x = 10
Step 3: Check
Plug in x into the original equation to verify it's a solution.
- Substitute in x: 72 = 5(10) + 22
- Multiply: 72 = 50 + 22
- Add: 72 = 72
Here we see that 72 does indeed equal 72.
∴ x = 10 is the solution to the equation.
