|x—1| —3 =7

|x—1|=4

\(\Rightarrow\)x-1=4,x-1=-4

x=5,x=-3

|x—2| + 5 = 17

|x—2|=12

\(\Rightarrow\)x-2=12,x-2=-12

x=14,x=-10

|x-1|-3=7

|x-1|   =7+3

|x-1|   =10

=>x-1=10

    x-1=-10

Khi x-1=10

      x   =10+1

     x     =11

Khi x-1=-10

      x   =(-10)+1

     x     =-9

=>x=11;x=-9

Ta có: 1 + 5 + 9 + . . . . . + x = 501501

 \(=>\frac{x\cdot\left(x+1\right)}{2}=501501\)\(=>x\cdot\left(x+1\right)=501501\cdot2\)\(=>x\cdot\left(x+1\right)=1003002\)

\(=>x\cdot\left(x+1\right)=1001\cdot1002\)\(=>x=1001\)
