Explanation Consider an example that the linear equation representing the variation of drinker’s BAC (Blood Alcohol Concentration) y with the number of hours x after 2 AM is y = − 0.015 x + 0.16 . The person is getting sobered up after drinking when y = 0 . Compute the value of x by substituting y = 0 in the equation y = − 0.015 x + 0.16 as, 0 = − 0.015 x + 0.16 Subtract 0.16 from both sides as, 0 − 0.16 = − 0.015 x + 0.16 − 0
