$|4x-11|=13$
By the definition of an absolute value:
$4x-11=13$ or $4x-11=-13\longrightarrow$ add 11 to each side
$4x-11+11=13+11$ or $4x-11+11=-13+11\longrightarrow$ add
$4x=24$ or $4x=-2\longrightarrow$ divide each side by 4
$4x\div4=24\div4$ or $4x\div4=-2\div4\longrightarrow$ divide
$x=6$ or $x=-0.5$
