Question

5(2-x)=35 bằng nhiêu ???

29x-13=45 bằng nhiêu???

Answer 1

5(2-x)=35

2-x= 35: 5

2-x= 7

x= 2-7

x=-5

29x-13=45

29x = 45+13

29x = 58

x= 58 : 29

x= 2

Answer 2

* 5(2 - x) = 35

2 - x = 35 : 5

2 - x = 7

x = 2 - 7

x = -5

* 29x - 13 = 45

29x = 45 + 13

29x = 58

x = 58 : 29

x = 2

Answer 3

5(2-x)=35

(2-x)=35:5

(2-x)=5

x =5-2

x = 3

29x-13=45

29x = 45+13

29x = 58

x =58:29

x =2

Answer 4

a, \(5\left(2x\right)=35\)

\(\Rightarrow2x=7\)

\(\Rightarrow x=3,5\)

b, \(29x-13=45\)

\(\Rightarrow29x=58\)

\(\Rightarrow x=2\)

Answer 5

\(5\left(2-x\right)=35\)

\(2-x=35:5\)

\(2-x=7\)

\(x=2-7\)

\(x=-5\)

\(29x-13=45\)

\(29x=45+13\)

\(29x=58\)

\(x=58:29\)

\(x=2\)
