Answer :

The equation with x about the number thought by Natasha is (x + 2.5) × 2 = 61

Let the number thought by Natasha be x. To formulate the equation, we will perform the same operations as done by Natasha. Forming the equation now -

(x + 2.5) × 2 = 61

Performing multiplication on Left Hand Side of the equation

2x + 5 = 61

Rewriting the equation

2x = 61 - 5

Performing subtraction on Right Hand Side of the equation

2x = 56

Rewriting the equation

x = 56/2

Performing division on Right Hand Side of the equation

x = 28

Thus, the equation is (x + 2.5) × 2 = 61 and the number thought by Natasha is 28.
