Answer:

the equation x - 18 = 4(x - 18)

Step-by-step explanation:

x - 18 = 4x - 72

x - 4x = - 72 + 18

- 3x = - 54

x = 54/3

x = 18

Sally had 36 postcards to begin with (18 + 18)

martha had 0 postcards to begin with

i feel like i did something wrong someone double check this but i think this is the answer.
