Question

He solution is n = –2 verified as a solution to the equation 1.4n + 2 = 2n + 3.2. What is the last line of the justification?

Answer 1

The answer is -0.8=-0.8

Explanation:

In order to get the answer, we would have to substitute the -2 in the equation for the n's! Hope you understand this!

Answer 2

`-0.8=-0.8`

Explanation:

We have been given that n=-2 verified as a solution to the equation
`1.4n+2=2n+3.2`.

As n=-2 is the solution for our given equation, so it will satisfy our equation.

Let us substitute n=-2 is our given equation.

`1.4*-2+2=2*-2+3.2`

`-2.8+2=-4+3.2`

`-0.8=-0.8`

Since the value of n satisfies our equation, therefore, last line of the justification will be
`-0.8=-0.8`.
