Question

1. 15 added to twice a number gives 35. Find the number.​

Answer 1

Answer:

10

Step-by-step explanation:

let the no. be x

twice the no. = x*2 = 2x

now, 15 is added

2x + 15 = 35

2x = 35 - 15

2x = 20

x = 20

2

x = 10

so, the no. is 10

Answer 2

Answer:

The required number is $10$.

Step-by-step explanation:

Given : $15$ added to twice a number gives $35$.

To find : The number =?

Solution :

• The condition is given that $15$ added to twice a number gives $35$.
• We have to find that number.
• Let, the number be $x$.
• According to given condition, the equation becomes

          $15+2x=35$

             ∴ $2x=35-15$

             ∴ $2x=20$

              ∴ $x=\frac{20}{2}$

              ∴ $x=10$

• ∴ The required number is $10$.
