Answer 2

Subtract 3.6 from both sides.

Explanation:

Given

`x + 3.6 = -1.7`

Required

Solve in one step

There are two ways to go about it.

1. Collect Like Terms

`x + 3.6 = -1.7`

3.6 and -1.7 are like terms, so the equation becomes

`x = -1.7 - 3.6`

`x = -5.3`

2. Subtract 3.6 from both sides

`x + 3.6 = -1.7`

This becomes

`x + 3.6 - 3.6 = -1.7 - 3.6`

`x = -5.3`

Hence, the last option answers the question.
