Question

If 15 is subtracted from a number, it becomes (-5). This statement is in the form of an equation

Answer 1

x-15=-5 is the answer

let the number be x

x-15=-5

by solving the equation

X=-5+15

X=10

Answer 2

If 15 is subtracted from a number, it becomes (-5). This statement in the form of an equation can be represented as x - 15 = (-5)

Solution,

• Let us assume the number from which 15 is subtracted be x.

• 15 subtracted from the number can be represented as ⇒ x - 15.

• Now, the result that is obtained after subtracting 15 from a number is -5.

Mathematically it can be represented as,

⇒   x - 15 = (-5).

• We can also find the number x by performing simple mathematical operations.

• -15 which is on the Left-Hand Side of the equation would be shifted to the Right-Hand Side of the equation and its sign would change from -15 to +15.

Therefore, we get x = -5 + 15 ⇒ 10.

Hence, the number from which 15 was subtracted was 10.
