Question

if we add 7 to twice a number we get 49 find the number​

Answer 1

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

Now, we are given that 7 is added to twice a number. So, we get the expression 2x+7. Now, we are given that if 7 is added to twice a number, we get 49. Therefore, the number is 21.

Answer 2

let the number be x

so,

$(2 \times x) + 7 = 49 \\ = > 2x + 7 = 49 \\ = > 2x = 49 - 7 \\ = > 2x = 42 \\ = > x = \frac{42}{2} \\ = > x = 21$

so, the number is 21.

Hope this helps you.
