Answer:

Step-by-step explanation:

since both equations are equal to the same thing, y, they are therefore equal to each other

so:

[tex]3x-5=2x-6\\x-5=-6\\x=-1\\[/tex]

substitute x, -1,  into either equation to solve for y

[tex]y=3(-1)-5\\y=-3-5\\y=-8[/tex]

or

[tex]y=2(-1)-6\\y=-2-6\\y=-8[/tex]

Therefore, the solution is (-1,-8)
