Solve the riddle. Dividing my dog’s age by 4 and adding 6 is the same as dividing my dog’s age by 8 and adding 8.

StartFraction x Over 4 EndFraction + 6 = StartFraction x Over 8 EndFraction + 8

How old is my dog?

- years old

16

Step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48
