We have found the constants for the equation relating X to t. Now we can solve for X. For convenience, continue to write k for the constant in the exponent. 150 – X 5 e180kt 4 %3D 120 – 2X 150 – X = (120 – 2X) e180kt 150 – X = 150e180kt_ Xe180kt 5X e180kt – X = 150e180kt – 150 :)- 5180kt - e180kt - 1) (e180kt – 1) X = 180kt - 1
