A bag is filled with green and blue marbles. There are 97 marbles in the bag. If there are 9 more green marbles than blue marble s, find the number of green marbles and the number of blue marbles in the bag.
2 answers:
97 + 9 = 106 So that means that there are 106 green marbles And to find the total You just add 106 + 97 Which equals 203 total marbles
Let the green marbles be G and the blue marbles be B 9 + G = B G+B=97 this brings us to simultaneous equation G = B-9 (using eq.1) sub into eq2 B-9+B=97 2B=106 B=53 if there are 53 blue marbles in the bag therefore there are 44 Green marbles
