Answer:

Maria had 105 beads

Step-by-step explanation:

Let x the number of beads Maria had

Let y the number of beads Farida had

We know because of the problem that

x + y = 250

x -18  = 3/5* y

x -3/5*y = 18

We solve this system of equation with a graphing tool

(intersection of both lines)

Answer

x = 105

y = 145
