Since the deepest point of Death Valley is below sea level, its altitude is negative. So, the difference between the altitudes is
![20320-(-280)](https://tex.z-dn.net/?f=20320-%28-280%29)
Subtracting a negative means to add, so we have
![20320-(-280)=20320+280=20600](https://tex.z-dn.net/?f=20320-%28-280%29%3D20320%2B280%3D20600)
Answer:
The proposed equation is solved as follows:
2X + 7 = 21
2X = 21 - 7
2X = 14
X = 14 / 2
X = 7
The value of X is 7.
A first degree equation is an algebraic equation in which each term is either a constant or a product of a fixed term on a single variable. Therefore, this equation is a first degree one, since it only has a single variable, which is X.
