write and solve an equation to determine how many blue marbles drew has.

Question

drew has 50 red, green, and blue marbles. he has six more red marbles than blue marbles and four fewer green marbles than blue.

Answer 1

Let the blue marbles be x

Red marbles = 6 + x

Green marbles = x - 4

According to the statement

x + (6 + x) + (x - 4) = 50

x + x + x + 6 - 4 = 50

3x + 2 = 50

3x = 50 - 2

3x = 48

x = 48/3

x = 16

So, the no. of blue marbles = 16

Answer 2

22 red ,16 blue and ,12 green
