This is a great graphing calculator: https://www.desmos.com/calculator Just put in the two equations and find their point of intersection(solution)

anonymous · Answer

u r basically going to compare ur y's. then u get a polynomial=0. at that point you can try factoring but the easiest is using the quadratic equation. this will give u ur x solutions and then u plug the x back into which ever equation to get y :)
