Question

A number is multiplied by 6. If 8 is subtracted from the product you get 34. What is the number? 4 6 7 8

A number is divided by 2. If 16 is added to the quotient you get 20. What is the number? 2 8 18 72

Answer 1

Let the number be x.

6*x - 8 = 34

6x - 8 = 34

6x = 34 + 8

6x = 42

x = 42/6

x = 7.


Let the number be y.

y/2

y/2 + 16 = 20

y/2 = 20 - 16

y/2 = 4

y = 2*4

y = 8.
