Question

Tìm \(x\in\mathbb{Z}\), biết :

a) \(x=\left(-1\right)+\left(-99\right)\)

b) \(x=\left(-105\right)+\left(-15\right)\)

Answer 1

a) \(x=-100\)

b) \(x=-120\)

Answer 2

a, \(x=\left(-1\right)+\left(-99\right)\)

\(x=-100\)

Vậy \(x=-100\)

b, \(x=\left(-105\right)+\left(-15\right)\)

\(x=-120\)

Vậy \(x=-120\)

Answer 3

a) x = -100

b) x = -120

Answer 4

a) x = -100

b) x = -120

Answer 5

a) x =100

b)x = 120

Answer 6

a) x = 1+99

x = 100

b) x = 105 + 15

x = 120

Answer 7

a)X=-1+-99=-100

B) X=-105+-15=-120

Answer 8

a) (-1) + (-99) = -(1 + 99) = -100. Vậy x = -100

b) (-105) + (-15) = -(105 + 15) = -120. Vậy x = -120

Answer 9

a, (-1) +(-99) = -(1+99) = -100.Vậy x = -100

b,(-105) + (-15) = -(105 + 15) = -120.Vậy x = -120

Answer 10

a, (-1) +(-99) = -(1+99) = -100.Vậy x = -100

b,(-105) + (-15) = -(105 + 15) = -120.Vậy x = -120
