Answer:
# yellow = 20
# blue = 23
# red = 5
Step-by-step explanation:
let 'r' = # red marbles
let '4r' = # yellow marbles
let '3+4r' = # blue marbles
r + 4r + 3 + 4r = 48
9r + 3 = 48
9r = 45
r = 5
red = 5
yellow = 4(5) = 20
blue = 3+4(5) = 23

Define jam and bread mix
------------------------------------------------------
Let the number of jar of jam be x
Let the number of packages of bread mix be y
------------------------------------------------------
Form equations and solve
------------------------------------------------------
x + y = 8 --------------------- (1)
6x + 5y = 45 ---------------- (2)
------------------------------------------------------
Rewrite equation to make x the subject
------------------------------------------------------
x+ y = 8
x = 8 - y ----------------------------(1a)
------------------------------------------------------
Substitute (1a) into (2)
------------------------------------------------------
6(8 - y) + 5y = 45
48 - 6y + 5y = 45
y = 48 - 45
y = 3
------------------------------------------------------
Substitute y = 3 into (1) to find x
------------------------------------------------------
x + 3 = 8
x = 8 - 3
x = 5
------------------------------------------------------
