19. Helen has 2 more than twice as many stamps as Gail. If Gail buys 10 more stamps, she and Helen will have the same
number of stamps. How many stamps does each person have
now?

x(Gail)=8 and y(Helen)=18

Step-by-step explanation:

2x+2=y and x+10=y

Plug y in and solve for x

2x+2=(x+10)

2x-x=10-2

x=8

Plug x in and solve for y

(8)+10=y

y=18

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

think about it deeply and passionately about this property

i am sorry
