Answer:
y = 800
x = 3
Explanation:
3(y + 200) = 3000
distribute the 3 to everything in parentheses
3y + 600 = 3000
subtract 600 from both sides
3y = 2400
divide both sides by 3
y = 800
---------------------------------
2(x + 5) = 16
distribute the 2 to everything in parentheses
2x + 10 = 16
subtract 10 from both sides
2x = 6
divide both sides by 2
x = 3
