Solve for x:
3x - 2 = 7
x = 3
Solve for x:
-2(x - 5) = 4
x = 3
Solve for x:
-6 - 2x = 5x + 8
x = -2
Solve for z:
w = y + x + z
z = w - y - x
Tanvi teaches art lessons at a day camp and needs to get supplies. She purchases 40 Bright Streak paint sets from the Color Splash art store. She uses a coupon she received in the mail for $10 off her purchase. Tanvi spends $310 in all.
Which equation can you use to find "p", the original price of each Bright Streak paint set?
A. 10(p-40) = 310
B. 40p - 10 = 310
C. 10p - 40 = 310
D. 40(p - 10) = 310
B

Valentina is trying to decide whether to join her school's swim team. During the summer, the team practices 4 days per week. Each of those days, they practice for 3 hours in the morning and practice again in the afternoon. They practice for a total of 20 hours each week.
Write an equation you can use to find "h", the length of each afternoon practice in hours?
4(h + 3) = 20

Brittany brought her collection of Map Mosaics jigsaw puzzles to a secondhand store to sell. She was paid cash for all 8 puzzles in her collection. Before she left, Brittany used $7.25 of her earnings to purchase a used board game. She had $12.75 remaining.
Write an equation she can use to find the amount of money, "p", Brittany received for each puzzle in her collection?
8p - 7.25 = 12.75
