t=1 or t=-3

Work Step by Step

First , we could minus both sides of the equation 1 , and get the equation 3/t+1/=6 , and then later divide both sides by 3 and get /t+1/=.2. Based on the property of both negative and positive input value could get positive absolute output value , we could get two conditions of the equations t+1=2 or t+1=-2 and we minus both sides of the equation 1 and can get the final answer t=1 or t=-3
