Answer:
The number of blue marbles = 33
Step-by-step explanation:
Let b represent blue marbles and r represent red marbles
there are b + r = 42 marbles in total
The number of number of blue marbles is 3 less than 4 times the number of red marbles
we can express it as b = 4r -3
Since there are b + r = 42 marbles in total and b = 4r - 3 we can rewrite the equation
b + r = 42
➡
r + 4r - 3 = 42
➡
5r - 3 = 42
➡
5r = 45
➡
r = 9 The number of red marbles = 9
The number of blue marbles 42 - 9 = 33
