Answer:

the solution is (5, 6)

Step-by-step explanation:

Please reserve " × " for representing multiplication, and " x " as a variable name.

Starting with the system

6x-5y= 0  

4×-5y = -10​

multiply the 2nd equation by -1.  This results in the system

6x - 5y  = 0  

-4x + 5y = 10

and combining these two equations results in

​ 6x - 5y  = 0  

-4x + 5y = 10

------------------

2x         = 10, or x = 5.

Substituting 5 for x in the first equation, we get

6(5) - 5y = 0, or 5y = 30.  Then y = 6, and the solution is (5, 6).
