A bag contains white marbles and green marbles, 52 in total. The number of white marbles is 3 less than 4 times the number of green marbles. How many white marbles are there?

Step-by-step explanation:

w + g = 52

w = 4g - 3

(4g - 3) + g = 52

5g - 3 = 52

5g = 52 + 3

5g = 55

g = 55/5

g = 11 ... there are 11 green marbles

w + g = 52

w + 11 = 52

w = 52 - 11

w = 41 <== = there are 41 white marbles

white marbles = 41

Step-by-step explanation:

Set up the equation

52 = (4g-3) + g

g = green marbles

white marbles are represented by 4g-3

these are added together to equal 52

solve for g, combine like terms

52 = 5g - 3

g = 11

4g - 3 = white marbles

(4x11) - 3 = white marbles = 41
