9x + 2y = 0
3x - 5y = 17
Multiply the second equation by -3 so now the system looks like:
9x + 2y = 0
-9x + 15y = -51
So now when we add the two equations together (in their like-terms columns), we are left with just one variable:
0x + 17y = -51
Solve for y:
17y = -51
y = -3
And plug y = -3 into either of the original equations to get the value of x:
9x + 2y = 0
9x + 2(-3) = 0
9x - 6 = 0
9x = 6
x = 2/3
So the answer is x = 2/3 and y = -3.

You cannot solve one linear equation with two variables.
It is not possible to solve a single linear equation in two variables.
There are several methods to solve linear equations, including the substitution method, elimination method, and graphical method. Additionally, matrix methods such as Gaussian elimination and using inverse matrices can also be employed for solving systems of linear equations. Each method has its own advantages depending on the complexity of the equations and the number of variables involved.
You need two independent linear equations to solve for two unknown variables.
You cannot solve one linear equation in two unknown variables.
