question 1)  divide the second system by 3 to find out.

anonymous · Answer

question 2) RE-WRITE the 2nd equation in a slope intercept form.

anonymous · Answer

question 3) divide each term by 3 and subtract x from both sides (all) in a second equation.

anonymous · Answer

and on. Like I mean you have to re-arrange and play with equations to set them in a form equivalent/similar to each other to see how many solutions the have.
