Solve for y

5x - 3y = -9

• y = 5/3x - 3

• y = 5/3x + 9

• y = 5/3x + 3

• y = 3/5x + 3

At a restaurant, the cost for a taco and a can of soda is $2.10. The cost of 2 tacos and 3 cans of soda is $5.15. Which system of equations can be used to determine the cost of a taco and a can of soda. Let x = cost of each taco and y = cost of each can of soda.

• x + y =5.15
  3x + 2y = 5.15
• x + y = 7.25
  2x + 3y = 5.15
• x + y = 2.10
  2x + 3y = 5.15
• 2x + 3y = 2.10
  x + y = 5.15
