Jeramy's algebra notes from a recent class were chewed up by the family dog. He found the scrap pictured below: S-2x + 3y = 18
23x - 3
Jeramy remembers that when the class graphed the system of equations, the two lines intersected at the point (6, 10).
Write an equation beginning with "3x –" that fits the situation as Jeremy remembers it.
Explain how you found your answer.
