Isolate absolute value: First, let's isolate the absolute value by moving the 9 to the other side of the equation.−8∣3x+2∣=−55−9−8∣3x+2∣=−64
Divide by −8: Now, divide both sides by −8 to get the absolute value by itself.∣3x+2∣=−64/−8∣3x+2∣=8
Set up equations: Next, we set up two equations to solve for the values inside the absolute value, because if ∣A∣=B, then A=B or A=−B. So we have: 3x+2=8 and 3x+2=−8
Solve first equation: Let's solve the first equation:3x+2=83x=8−23x=6x=36x=2
Solve second equation: Now, let's solve the second equation:3x+2=−83x=−8−23x=−10x=3−10x=−310 or −3.33…
