Question

Tìm x:

a) 5-x=8

b) x-(-2)=16

c) 219-(x+1)=100

Answer 1

a) 5 - x = 8

=> x = -3

Vậy x = -3

b) x - ( -2 ) = 16

=> x + 2 = 16

=> x = 14

Vậy x = 14

c) 219 - ( x + 1 ) = 100

=> x + 1 = 119

=> x = 118

Vậy x = 118

Answer 2

a) 5 - x = 8

   x = 5 - 8

   x = -3

b) x - ( - 2 ) = 16

   x + 2 = 16

   x = 16 - 2

   x = 14

c) 219 - ( x + 1 ) = 100

   x + 1 = 219 - 100

  x + 1 = 119

   x = 119 - 1

   x = 118 

Answer 3

\(a,5-x=8\)

            \(x=5-8\)

            \(x=-3\)

\(b,x-\left(-2\right)=16\)

             \(x+2=16\)

                     \(x=16-2\)

                     \(x=14\)

\(c,219-\left(x+1\right)=100\)

                      \(x+1=219-100\)

                      \(x+1=119\)

                              \(x=118\)
