The cost, in dollars, to rent a kayak is proportional to the number x of hours you rent the kayak. it costs $27 to rent the kayak for 3 hours. write an equation that represents y.

Use the elimination method to solve the systems of equations.choose the correct ordered pair. 7x+4y=39

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.
