Question

Tìm số nguyên x biết

X + (- 35 ) = 18

- 2x -(- 17)= 15

Answer 1

X + (- 35 ) = 18

X - 35 = 18

       X = 18 + 35

       X = 53

Vậy X = 53

- 2x -(- 17)= 15

- 2x + 17 = 15

- 2x = 15 - 17

- 2x = - 2

    x = - 2 : ( - 2 )

    x = 1

Vậy x = 1

Answer 2

1) x+ (-35)=18

<=> x-35=18

<=> x=53

2) -2x-(-17)=15

<=> -2x+17=15

<=> -2x=-2

<=> x=1

Answer 3

a)X + (- 35 ) = 18

x = 18 + 35

x = 53

b)- 2x -(- 17)= 15

-2x = 15 - 17

-2x = -2

x = 1

hok tốt!!!

Answer 4

a, 

  \(x+\left(-35\right)=18\)

 \(x=18+35\)

 \(x=53\)

b, 

\(-2x+17=15\)

\(-2x=15-17\)

     \(2x=2\)

       \(x=1\)

Answer 5

x + (-35) = 18

x = 18 - ( -35 )

x = 53

-2x - (-17) = 15

-2x + 17 = 15

-2x = -2

=> x = 1
