Question

If we add 7 to twice a number we get 49 express it in simple equation

Answer 1

Required number = 21

Step-by-step explanation:

Let the number be x.

Twice the number = 2x

Adding 7 to twice the number = 2x + 7

Now , according to the problem given,

Add 7 to twice the number, we get 49

=> 2x + 7 = 49

/* Subtract both side by 7, we get

=> 2x + 7 - 7 = 49 - 7

=> 2x = 42

/* Divide both sides by 2, we get

=> x = 21

Therefore,

Required number = x = 21

Answer 2

Answer:

Step-by-step explanation:

(7+7)+x=49

14+x=49

x=49-14

x=35
