Step-by-step explanation:
It is true that To "Derive" means to get an equation from a specific information.
<u>Explanation:</u>
If we have an equation, we can easily answer various questions. The equation is derived by the data given, observations, results and assumptions. We also need to consider the law and theories while deriving an equation. While deriving an equation, the dependent and independent variables are arranged accordingly.
<u>Example</u> - To derive the formula of a quadratic equation.
- To derive something that is not an equation means to come to a conclusion from the results of the data obtained.
Answer:
x = 11, y=-½
Step-by-step explanation:
Simultaneous equations - subtract the first equation from the second.
x + 4y = 9
-(x - 2y = 12)
6y = -3
y = -½
Substitute y
x + 4(-½) = 9
x + -2 = 9
x = 11
