Answer provided by our tutors
let
r = the number of red beads sheila has
g = the number of green bead sheila had
the number of red beads sheila has is four times as many as the number of green beads she has
r = 4g
there are 75 red and green beads
r + g = 75
by solving the system of equations
r = 4g
r + g = 75
we find
r = 60 red beads
g = 15 green beads
