Answer:

Step-by-step explanation:
Let
x------> the number of blue cards
y-----> the number of green cards
we know that

isolate the variable y
-----> equation A
we have
substitute the value of x in the equation A to find the value of y

Answer:
x = 2
Step-by-step explanation:
Given
1 + 4x = - 5 + 7x ( subtract 7x from both sides )
1 - 3x = - 5 ( subtract 1 from both sides )
- 3x = - 6 ( divide both sides by - 3 )
x = 2

Step-by-step explanation:
The next three terms are: 1/6 , 0 and -1/6
Step-by-step explanation:
Given sequence is:

First of all, we have to find the common difference

The common difference is -1/6
We can simply add -1/6 to the previous term to find the next terms so,
Adding -1/6 to 1/3

Hence,
The next three terms are: 1/6 , 0 and -1/6
