Understand absolute value equation: Understand the absolute value equation.Absolute value equations have two possible solutions because the expression inside the absolute value can be either positive or negative to equal 16.∣3x+4∣=16
Set up separate equations: Set up two separate equations to solve. 3x+4=16 and 3x+4=−16
Solve first equation: Solve the first equation 3x+4=16.3x=16−43x=12x=312x=4
Solve second equation: Solve the second equation 3x+4=−16.3x=−16−43x=−20x=3−20x=−6.67
