`|(-11)/15 + x| - 40/23 = (-17)/23`
`=> |(-11)/15 + x| = (-17)/23 + 40/23`
`=> |(-11)/15 + x| = 23/23`
`=> |(-11)/15 + x| = 1`
`=>` \(\left[ \begin{array}{l}(-11)/15 + x = 1\\(-11)/15 + x= -1\end{array} \right.\)
`=>` \(\left[ \begin{array}{l}x = 1 - (-11)/15\\x= -1 - (-11)/15 \end{array} \right.\)
`=>` \(\left[ \begin{array}{l}x = 26/15\\x= (-4)/5 \end{array} \right.\) (T/M)
