Question

giúp em câu này

d) 135 – 5(x + 4) = 35

e) 25 + 3(x – 8) = 106

f) 2x – 49 = 5. 32

Answer 1

d)5( x+4)=135-35

       x+4=100:5

       x    =20-4

      x     =16

Answer 2

d) 135 - 5 (x+4) = 35

5 (x+4) = 135 - 35

5 (x+4) = 100

(x+4) = 100 : 5

x + 4 = 20

x = 20 - 4

x = 16

e) 25 + 3 ( x - 8 ) = 106 

3  ( x - 8 ) = 106 - 25 

3  ( x - 8 ) = 81 

x - 8 = 81 : 3 

x - 8 = 27 

x = 27 + 8 

x = 35 

f) 2x – 49 = 5. 32

2x - 49 = 160

2x = 160 + 49

2x = 209

x = 209 : 2

x = 104,5

Answer 3

d)\(135-5\left(x+4\right)=35\)

⇔\(5\left(x+4\right)=100\)

⇔\(x+4=20\)

⇔\(x=16\)

e)\(25+3\left(x-8\right)=106\)

⇔\(3\left(x-8\right)=81\)

⇔\(x-8=27\)

⇔\(x=35\)

f)\(2x-49=5.32\)

⇔\(2x-49=160\)

⇔\(2x=209\)

⇔\(x=\dfrac{209}{2}\)
