Answer:
So, instead of balloons, I will be taking variables, hope no problem for you.
Let us take blue balloon as x, green as y, and yellow as z.
So, first eqn, x + y = 10
Second, y + y = 10
2y = 10
y = 5(green balloon)
Third eqn, y + z = 5
5 + z = 5
z = 5 -5
z = 0(yellow balloon)
Substitute y in first eqn
x + 5 = 10
x = 10 - 5
x = 5(blue balloon)
