Answer:
one solution
Step-by-step explanation:
3x − 7 = 4 + 6 + 4x
Combine like terms
3x-7=4x+10
Subtract 3x from each side
-7=x+10
Subtract 10 from each side
-17 =x
There is one solution

Answer: 
Step-by-step explanation:
Given : In the Sahara Desert one day it was 136°F.
In the Gobi Desert a temperature of -50°F was recorded.
Clearly , 136°F> -50°F
Then, the difference between these two temperatures will be :-
![136^{\circ}F-(-50)^{\circ}F\\\\=(136+50)^{\circ}F\ \ [\because \text{Product two neagtive sign is positive]}\\\\=186^{\circ}F](https://tex.z-dn.net/?f=136%5E%7B%5Ccirc%7DF-%28-50%29%5E%7B%5Ccirc%7DF%5C%5C%5C%5C%3D%28136%2B50%29%5E%7B%5Ccirc%7DF%5C%20%5C%20%5B%5Cbecause%20%5Ctext%7BProduct%20two%20neagtive%20sign%20is%20positive%5D%7D%5C%5C%5C%5C%3D186%5E%7B%5Ccirc%7DF)
Hence, the difference between these two temperatures =
