Step-by-step explanation:
Answer: There are 29 green marbles.
Step-by-step explanation:
x: green marbles
y: blue marbles
So we have an equation:
x + y = 40
while,
2y = x - 7
so set this equation equal to x, we have
x = 2y + 7
replace x into 2y + 7 for the first equation
and this is how it looks:
(2y + 7) + y = 40
2y + y = 40 - 7
3y = 33
y = 11
x = 40 - y
x = 40 - 11
x = 29
