Lindsay had $40. She works at the grocery store and earns $15 each day.
Which equation shows the relationship between Lindsay's savings (y) and the number of days Lindsay works (x)?

• y = 15x + 40

• x = 15y + 40

• y = 40x + 15

• y = 40 - 15x

To solve the equation below, you would...
x - 62 = 123

• add 62 to each side

• subtract 62 from each side

• multiply each side by 62

• Add 123 to each side
