Hi everybody,
Please I want to Solve the system:
3x-2y=19
y3-2x=19
x,y real number!
Thank you !

The first equation below is wrong, so everything below it is also invalid.naoufelabs said:3x-2y=19

naoufelabs said:Please I want the steps to find it, because I'm stumbled in the last steps as follow:
x*Ln(3)-y*Ln(2)=Ln(19)
3*Ln(y)-x*Ln(2)=Ln(19)
x*Ln(3)-y*Ln(2) - 3*Ln(y)-x*Ln(2) = 0
x*Ln(3)+x*Ln(2) = y*Ln(2)+3*Ln(y) {each one equals Ln(19)}
x*Ln(3)+x*Ln(2) = y*Ln(2)+3*Ln(y) = Ln(19)
x*Ln(6) = y*Ln(2)+3*Ln(y) = Ln(19)
x = ln(19)/ln(6)
...
Here I'm stumbled.
Thank you for your response.
To solve a system of equations, you need to find the values of the variables that make both equations true. This can be done by using different methods such as substitution, elimination, or graphing.
A one-variable system of equations involves only one variable, while a two-variable system of equations involves two variables. This means that the first equation will have one variable and the second equation will have two variables.
Yes, a system of equations can have any number of equations. The number of equations will depend on the number of variables and the complexity of the problem being solved.
The purpose of solving a system of equations is to find the intersection point or points where both equations are true. This can be useful in finding the values of variables in real-world problems or in understanding the relationship between different variables.
Some common mistakes to avoid when solving a system of equations are not carefully copying down the equations, making calculation errors, and forgetting to check the solution in both equations. It is also important to keep track of the variables and their corresponding values throughout the solving process.
