Answer: The given equations are not valid because there is no equal sign between the first and second equation. If you are trying to solve a system of equations it should be in the form of
3x + 5y = - 9
-6x - 5y = 18
You can solve for x and y by using different methods such as substitution, elimination or graphing.
In this case, you can add the first equation to the second equation:
3x + 5y = -9
-6x - 5y = 18
-3x = 27
x = -9
Now you can substitute this value of x into one of the equations to find the value of y.
3x + 5y = -9
3(-9) + 5y = -9
-27 + 5y = -9
5y = 18
y = 3.6
So, the solution is x = -9 and y = 3.6
It's important to check your solution by substituting the values of x and y in the original equations to make sure that the solution is consistent.
