For your first question: 3X- 7 = 3 (x = 1) I'm not sure if it's a typo and the equal sign should be a minus sign.

For the second question, is that three separate questions? 

For your third question: solve for y first (isolate it out)

  • so subtract 2x from both sides giving you: 7y = -2x+14
  • Then divide by 7, giving you: y= -2/7x + 2
  • So your y-intercept is 2
