Which of the following statements describes a correct method for solve this equation?

15 + 3x = 18

1 answer

To solve the equation 15 + 3x = 18, you can follow these steps:

1. Start with the equation: 15 + 3x = 18
2. Subtract 15 from both sides of the equation to isolate the variable term: 15 - 15 + 3x = 18 - 15
3. Simplify: 3x = 3
4. Divide both sides of the equation by 3 to solve for x: (3x)/3 = 3/3
5. Simplify: x = 1

Therefore, the correct method to solve this equation is x = 1.
