Question

Which property of equality was used to solve this equation? x − 5 = -14 x − 5 + 5 = -14 + 5 x = -9

Answer 1

Additive property

Explanation:

Given

`x - 5 = -14`

Required

The property used

In the 2nd step, 5 was added to both sides, i.e.

`x - 5+5 = -14 + 5`

The above is an illustration of additive property of equality, i.e. Adding or subtracting the same variable or constant to both sides of an equation
