The equation given is a linear equation with one variable, x. To solve the equation, we need to eliminate the denominators by finding a common denominator. The least common denominator for 15, 20, and 60 is 60. Multiplying both sides of the equation by 60 will eliminate the denominators. After simplifying, we find that 4x + 24 = 23. Subtracting 24 from both sides gives us 4x = -1. Dividing both sides by 4, we find that x = -1/4. Therefore, the correct answer is x = -1/16.
