a. \(14-\)\(\left|x\right|\)\(=-\left(11-17\right)\)
\(14-\)\(\left|x\right|\) \(=-\left(-6\right)\)
\(14-\)\(\left|x\right|\) \(=6\)
\(\left|x\right|\) \(=14-6\)
\(\left|x\right|\) \(=8\) \(\Rightarrow x=8,x=-8\) Vậy........
\(-\left(-15\right)\) \(+\left|x\right|=-\left(21-14\right)\)
\(15+\left|x\right|=-\left(-35\right)\)
\(15+\left|x\right|=35\)
\(\left|x\right|=35-15\)
\(\left|x\right|=20\)
\(\Rightarrow x=20,x=-21\)
Vậy......
\(6-\left(\left|x\right|-1\right)=-9\)
\(\left(\left|x\right|-1\right)=6-\left(-9\right)\)
\(\left(\left|x\right|-1\right)=6+9\)
\(\left|x\right|-1=15\)
\(\left|x\right|=15+1\)
\(\left|x\right|=16\)
\(\Rightarrow x=16,x=-16\)
Vậy.....
\(-5+\left|x-4\right|=-\left(-18\right)\)
\(-5+\left|x-4\right|=18\)
\(\left|x-4\right|=18-\left(-5\right)\)
\(\left|x-4\right|=18+5\)
\(\left|x-4\right|=23\)
\(\Rightarrow x-4=23,x-4=-23\)
✽ \(x-4=23\Leftrightarrow x=25\)
✽\(x-4=-23\Leftrightarrow x=-19\)
Vậy \(x=25,x=-19\)
