Samaria has 6 more than three times as many pieces of candy as sydney. samaria has 36 pieces of candy. how many does sydney have

3 * Sydney + 6 = Samaria

3*x + 6 = 36

3*x = 36 - 6 = 30

x = 30/3

x = 10

Sydney has 10 pieces of candy.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
