Question

Match the justification to each statement in the solution of x+12.7 = -25.2

Answer 1

Answer: x+0= -37.9/ additive inverse/simplification

X+12.7= -25.2 / given

X=37.9 / identify property of addition

X+12.7-12.7=-25.2-12.7 / subtraction property of equality

Explanation:

Answer 2

For this case we have the following equation:

`x + 12.7 = -25.2`

To solve we follow the steps below:

Step 1:

We subtract 12.7 on both sides of the equation:

`x + 12.7-12.7 = -25.2-12.7`

Step 2:

We add similar terms, taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the sign of the major is placed.

So:

`x + 0 = -25.2-12.7\\x = -37.9`

Finally, the result is:
`x = -37.9`

Answer:

`x = -37.9`
