According to a certain tractor maintenance manual, the hydraulic pressure system should be 4,425.5 psi with an absolute error of 75.5 psi. Write an absolute value equation that will give the minimum and maximum hydraulic pressure.

Let x be the actual hydraulic pressure.

We have been given that the measured hydraulic pressure is 4,425.5 psi and the absolute error is 75.5 psi.

Absolute value equation is:

| Actual value - Measured value | = Absolute error

Hence, required equation is:

| x - 4425.5 | = 75.5
