$|x-1|+|x-3|=2\\\\\left \{ {{x-1+x-3=2} \atop {\left \{ {{x-1\geq 0} \atop {x-3\geq 0}} \right.}} \right. , \left \{ {{x-1-x+3=2} \atop {\left \{ {{x-1\geq 0} \atop {x-3\leq 0}} \right.}} \right. , \left \{ {{-x+1+x-3=2} \atop {\left \{ {{x-1\leq 0} \atop {x-3\geq 0}} \right.}} \right. ,\left \{ {{-x+1-x+3=2} \atop {\left \{ {{x-1\leq 0} \atop {x-3\leq 0}} \right.}} \right.$

$\left \{ {{2x=6} \atop {\left \{ {{x\geq 1} \atop {x\geq 3}} \right.}} \right. , \left \{ {{0x=0} \atop {\left \{ {{x\geq 1} \atop {x\leq 3}} \right.}} \right. , \left \{ {{0x=4} \atop {\left \{ {{x\leq 1} \atop {x\geq 3}} \right.}} \right. ,\left \{ {{-2x=-2} \atop {\left \{ {{x\leq 1} \atop {x\leq 3}} \right.}} \right.$

$\left \{ {{x=3} \atop {x\geq 3}} \right. , \left \{ {{0x=0} \atop {1\leq x\leq 3}} \right. , \left \{ {{0x=4} \atop {x\leq 1, x\geq 3}} \right. , \left \{ {{-2x=-2} \atop {x\leq 1}} \right.$

x=3, x ∈ [1; 3], x ∈ ∅, x ∈ ∅

x ∈ [1; 3]

$|x^2-5x|=6\\\left \{ {{x^2-5x-6=0} \atop {x^2-5x\geq 0}} \right. , \left \{ {{x^2-5x+6=0} \atop {x^2-5x\leq 0}} \right. \\\left \{ {{\left \{ {{x=-1} \atop {x=6}} \right. } \atop {\left \{ {{x\leq 0} \atop {x\geq 5}} \right. }} \right. , \left \{ {{\left \{ {{x=2} \atop {x=3}} \right. } \atop {\left \{ {{x\geq 0} \atop {x\leq 5}} \right. }} \right.$

x = -1, x = 6, x = 2, x = 3

$|x+3|$

x ∈ ∅, x ∈ ∅
