5 System of Equations Find two points that are a solution to the system: y  x 2 – x – 6 y < 2 x – 2 What do you already know about this? How can you use what you already know to solve the problem?

©Evergreen Public Schools System of Equations Darren opened a savings account with 100 at Dollar Federal Savings Bank where he earns at least 4% annual interest on his savings. Erin opened keeps her money in a jar at home. She has $150 and adds up to $5 each year. Find 3 solutions for when Darren has more in his account than Erin. In each year, how much does he have?
