Question

Five times the sum of some number and 2 is equal to 9 times the number minus 22

Answer 1

Answer:  7

Step-by-step explanation:

5(x + 3) =8x - 6

 

5x + 15 = 8x - 6

 

5x + 21 = 8x

 

21 = 3x

 

x = 7

Answer 2

Answer:

The unknown (some) number = 52

Step-by-step explanation:

let the some number = x

given that,

5(x+2) = 9(x-22)

=> 5x+10 = 9x-198

=> 9x-5x = 10+198

=> 4x = 208

=> x = 208/4

=> x = 52

so, the unknown (some) number = 52
