Answer:

I believe it may be 4.2

Step-by-step explanation:

5x + 14 = -7

5x + 14 - 14= - 7 -14

5x = -21

5x = 5x

x = 4.2

Answer:

x = -21/5

Step-by-step explanation:

It'd be best to present your question as follows:  Solve 5x + 14 = -7 for x.

To do this, subtract 14 from both sides, obtaining 5x = -21.  Then x = -21/5.
