Answer:
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
Answer:
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
