For a particular car, the linear function f gives the predicted power, in brake horsepower (bhp), for engine speeds between 1,000 revolutions per minute (rpm) and 6,000 rpm. According to this function, the car's predicted power is 228 bhp at an engine speed of 1,896 rpm and 600 bhp at an engine speed of 4,500 rpm. The equation \( f\left(x\right)=\frac{1}{7}\left(x-a\right)+228 \) defines f, where x is the engine speed, in rpm, and a is a constant. What is the value of a?
