3. Let's tell and write the answers as quickly as possible a) If x = 2y, then x + y in terms of y =
b) If x = 3y, then 2xy in terms of y
c) If a = 2b and b = 3, then a + b
= ...
d) If p = 3q and q = 2, then p-q

Step-by-step explanation:

a) If x = 2y, then x + y

In terms of y

2y + y

3y

b) If x = 3y, then 2xy

In terms of y

2(3y)(y)

6y²

c) If a = 2b and b = 3, then a + b

a + b

2b + b

2(3) + 3

9

d) If p = 3q and q = 2, then p-q

p-q

3q - q

2q

4

the equivalent expression are always the hardest ones but you look at the gcf also
