Solve the following system of equations below x-2y=3 2x-3y=9

(9, 3)

Step-by-step explanation:

I'd strongly suggest that you write these two equations one above the other:

x-2y=3

2x-3y=9

Let's eliminate x by addition / subtraction:  Multiply the first equation by -2 to obtain -2x in the first row over +2x in the second row:

-2x + 4y = -6

2x -  3y =  9

           y = 3

Now subst. 3 for y in the first equation:  x - 2y = 3 becomes:

x - 2(3) = 3, or

x = 6 + 3  =  9

The solution is (9, 3).

{3 + i, 3 - i, 3, -1}
