Question

if we add 7 to twice number we get 99​

Answer 1

$\large\fbox\red{Answer}$

Let the number be x.

So twice a number be 2x .

According to the question :

$2x + 7 = 99 \\ \\ = > 2x = 99 - 7 \\ \\ = > 2x = 92 \\ \\ = > x = \frac{92}{2} \\ \\ = > x = 46$

Answer 2

Answer:

46

Step-by-step explanation:

Let the Number be 'n'

Thus  7 + 2n = 99

        2n = 99 - 7

        2n = 92

         n = $\frac{92}{2}$

         n = 46

Thus if 46  is added twice to 7 we get 99.

Verification

(46 × 2 )+7   = 99

(92) + 7   =   99

99  =  99

Thus LHS   =   RHS
