I think that you can solve your system of equation using the substitution method

anonymous · Answer

That is what I thought.

michele_laino · Answer

Ok! x=1 and y=-2

michele_laino · Answer

the point (1,-2) is the point in which the lines intersect each other

anonymous · Answer

So now in part A i must show my steps...

michele_laino · Answer

(1)    $$3x-5=6x-8$$
(2)  $$3x=3$$
(3)  $$x=1$$
(4) $$y=3*1-5=6*1-8=-2$$
