Question

a) (158 - X ) : 7 = 20

b) 5. X + 35 = 330

 

Answer 1

a) (158-x):7=20`

`=> 158-x=20 . 7`

`=> 158-x=140`

`=> x=158-140`

`=> x=18`

Vậy `x = 18`

`b)5x+35=330`

`=> 5x=330-35`

`=> 5x=295`

`=> x=295:5`

`=> x=59`

Vậy `x=59`

Answer 2

(158-x):7=20

158-x=20x7

158-x=140

x=158-140

x=18

Vậy x=18

b,5.x+35=330

5.x=330-35

5.x=295

x=295:5

x=59

Vậy x=59

Answer 3

\(a,\left(158-x\right)=20\times7\)

\(158-x=140\)

\(x=158-140\)

\(x=14\)

\(b,5.x+35=330\)

\(5.x=330-35\)

\(5.x=295\)

\(x=295:5\)

\(x=59\)
