Question -:

If we add 7 to twice a number, we get 49. Find the number.

$\huge\bold{\mathfrak{\purple{A{\pink {n {\green {s{\blue{w{\red{e {\orange {r}}}}}}}}}}}}}$

Let the number be x.

Twice the number = 2x.

Adding 7, we get 2x + 7.

As mentioned, the result is 49.

So,

By the problem,

$2x + 7 = 49$

$2x = 49 - 7$

$2x = 42$

$x = \frac{42}{2}$

$x = 21$

Hope it helps! :)
