You would have to have common demoniators to add.

How many solutions does the following equation have?<br> -4(+5) = -4- 20
Rus_ich [418]

Answer:

0

Step-by-step explanation:

Try looking at it in 2 ways- left side and right side. On the left side we have -4*5, which equals -20. On the right we have -4-20, which equals -24. so then when we add it all together (not literally) we get -20=-24. Since -20 and -24 obviously do not equal eachother, there is no solution.
