Question

Answer 1

c) \(5\left(x+12\right)+22=92\)

\(5\left(x+12\right)=92-22\)

\(5\left(x+12\right)=70\)

\(x+12=70:5\)

\(x+12=14\)

\(x=14-12\)

\(x=2\)

d) \(250-10\left(24-3x\right):15=244\)

\(10\left(24-3x\right):15=250-244\)

\(10\left(24-3x\right):15=6\)

\(10\left(24-3x\right)=6\cdot15\)

\(10\left(24-3x\right)=90\)

\(24-3x=90:10\)

\(24-3x=9\)

\(3x=24-9\)

\(3x=15\)

\(x=15:3\)

\(x=5\)

Answer 2

c) 5. ( x + 12) + 22 = 92

5.( x + 12) = 92 - 22

5.( x + 12) = 70

x + 12 = 70 : 5

x + 12 = 14

x = 14 - 12

x = 2

d) 250 - 10 . ( 24 - 3x) : 15 = 244

 10 . ( 24 - 3x) : 15 = 250 - 244 

10 . ( 24 - 3x) : 15 = 6

10 . ( 24 - 3x) = 6 x 15

10 . ( 24 - 3x) = 90

 24 - 3x = 90 : 10

24 - 3x = 9

3x = 24 - 9

3x = 15

x = 15 : 3

x = 5

 

 

Answer 3

Answer 4

`5(x+12)+22=92`

`=> 5(x+12)=92-22`

`=>5(x+12)=70`

`=>x+12=70:5`

`=> x + 12 = 14`

`=> x = 14-12`

`=> x = 2`

`250-10(24-3x):15=244`

`=> 10(24-3x):15=6`

`=>10(24-3x)=90`

`=>24-3x=9`

`=>3x=15`

`=>x=5`

Answer 5

c

\(5\cdot\left(x+12\right)=70< =>x+12=14< =>x=2\)

d)

\(240\cdot\left(24-3x\right):15=244< =>10\cdot\left(24-3x\right):15=6< =>10\cdot\left(24-3x\right)=90< =>24-3x=9< =>3x=15< =>x=5\)

Answer 6

c) 5 . ( x + 12 ) + 22 = 92

5 . ( x + 12 ) = 92 - 22 = 70

x + 12 = 70 : 5 = 14

x = 14 - 12 = 2
