Answer:

x=-2

Step-by-step explanation:

4+5x=-16-5x

Add 5x to the other side

4+10x=-16

Then subtract 4 to the other side

10x=-20

Divide -20 by 10

x=-2

Answer:

x= -2

Step-by-step explanation:

first you have to isolate the variable so you add 5x to both sides. then you subtract 4 from both sides, so you get 10x= -20. divide 10 from both sides and you get x= -2.
