June has a total of 35 marbles. She has 4 times as many blue marbles as green marbles. She writes the following system of equations to represent the situation.

{b+g=35
b=4g
What method would you use to solve this equation? Explain your answer.

June has 7 green and 28 blue marbles

Step-by-step explanation:

b + g = 35

b = 4g

Use substitution method to solve them simultaneously

4g + g = 35

5g = 35

g = 7

b = 4g = 4(7) = 28

b = 28, g = 7

She has 7 green and 28 blue marbles
