a) 10 b) 11 c) 12 d) 6

Respuesta :

Answer:

b) 11

Step-by-step explanation:

Let the number Nalini thinks of be x.

Doubles number and adds 5 = sixteen more than the number

2x + 5 = x + 16

Shift the (+5) to the other side and change to (-5).

Shift the (x) to the other side and change to (-x).

2x - x = 16 - 5

Evaluate like terms.

x = 11

Answer:

11

Step-by-step explanation:

Think the number is x

According to the question

2x+5=x+16

2x-x=16-5

x=11
