Question

If 5 is added to twice of a number it becomes 6 , then the number is ?

Answer 1

Let x = the number

Then 6[5+2x] = -16x + 2

30 + 12x = -16x + 2

28x = -28

x = -1

Answer 2

Answer:

Let the number be x

Thus, 2x + 5 = 6

= 2x = 6 - 5

= 2x = 1

= x = 1/2

∴ x = 1/2

∴ The number = 1/2
