• x = -3

• x = -4

Simplify

- (x + 2) + 3x + 8

• 4x + 10

• 2x + 6

Write an equation

Christian has $1200 set aside in a savings account and earns $400 each week. If Christian donates $200 to charity, and spends $410 each week, how many weeks can he continue to spend without running out of money?

• 1200 + 400w = 200 + 410w

• 1200 - 400w = -200 + 410w

• 1200w - 400 = 200w - 410

• 1200 + 410w = 200 + 400w

Write an equation

Tamera has two amusement parks to choose from. The first charges $8 per hour, and they give a $3 student discount off the total price. The second charges $7.25 per hour. How many hours would Tamera have to stay at each park for the cost to be the same?

• 3x + 8 = 7.25

• 8x - 3 = 7.25x

• 7.25x + 3x = 8

• 8x + 3 = 7.25x
