Answer:

36 green marbles

Step-by-step explanation:

Let b = number of blue marbles

g= number of green marbles

g = 4b+8

The total is 43

g+b = 43

Substitute 4b+8 in for g

4b+8 +b = 43

Combine like terms

5b +8 = 43

Subtract 8 from each side

5b+8-8 = 43-8

5b = 35

Divide each side by 5

5b/5 = 35/5

b=7

There are 7 blue marbles

Now we need to find the green marbles

b+g=43

43-b =g

43 -7 =36
