Final answer:
The given equation 45+60=15x+15x simplifies to 105=30x. By dividing both sides by 30, we find that x equals 3.5. This solution is not listed in the provided multiple-choice options.
Step-by-step explanation:
The equation given is 45+60=15x+15x. To find the value of x, we start by simplifying both sides of the equation. Add 45 and 60 to get 105 on the left-hand side. Combine like terms on the right-hand side, 15x + 15x, to get 30x.
The equation now reads: 105 = 30x. Now, divide both sides of the equation by 30 to isolate x. So, x equals 105 divided by 30, which simplifies to 3.5.
Step-by-Step Solution:
- Add 45 and 60 to obtain 105.
- Combine like terms on the right-hand side (15x + 15x) to get 30x.
- Divide both sides by 30.
- The result is x = 3.5.
Therefore, the correct answer is that x equals 3.5, which is not present in the provided options A to D.
