To find the x or x's values
3r - 9r = 18 wright equaton -6r = 18 combine like terms r = -3 solve
if the equation was 7x = 42. The answer would be x = 6
NaHCO3 + H2O = H2CO3 +OH + Na
To find the volume on a rectangular prism, the equaton is: length*width*height
You cannot "solve" a mean squared deviation". You can calculate it or use it, but there is nothing to solve!
Analyzing it!
The balanced equation for the reaction between C8H7O and water is: C8H7O + 8H2O → 8CO2 + 9H2O.
solve means workout the answer to a math question
You cannot solve probability since it is not a question! It is like asking how you can solve history!
If you have an equation where a variable alone is squared and the other side is a negative, you cannot solve that equaton because it's impossible to take the square root of a negative number. So yes, it's no solution.
To answer something
Calculate; find; solve.
