True
General Formulas and Concepts:
Order of Operations: BPEMDAS
Explanation:
In order to verify x, simply plug it back into the original equation to see if the equation would be true.
Step 1: Define
Original Function: x + 2x + 3 = 4x - 12
x = 15
Step 2: Verify
- Substitute: 15 + 2(15) + 3 = 4(15) - 12
- Multiply: 15 + 30 + 3 = 60 - 12
- Add: 48 = 60 - 12
- Subtract: 48 = 48
Since 48 does indeed equal to 48, 15 would be a solution. Therefore, x = 15 is verified and true.
