Answers: 1
![\bf |18x+9| + 1 64\implies \pm(18x+9)+164 \\\\[-0.35em] ~\dotfill\\\\ +(18x+9)+164\implies 18x+1064\implies 18x 54 \\\\\\ x \cfrac{54}{18}\implies \boxed{x 3} \\\\[-0.35em] ~\dotfill\\\\ -(18x+9)+164\implies -18x-9+164\implies -18x-864 \\\\\\ -864+18x\implies -72 18x\implies \cfrac{-72}{18}=x\implies \boxed{-4x}](/tpl/images/0295/7294/770fe.png)
