1) Solve the system of equation using elimation:

2x + y = 1

-3x - 2y = -4

Initialize the values 'x' and 'y' below.

2) Suppose an arithmetic sequence has first value = 10 and common difference = 4.

10, 14, 18….

What is the 40th value in the sequence?

Appropriately initialize the value 'value' that represents the 40th term in the sequence.

3) Suppose the 5th value of an arithmetic sequence is 30 and the 7th value of the sequence is 36. Appropriately initialize the value of 'firstVal' which represents the first value in this sequence. 

4) Suppose the 5th value of an arithmetic sequence is 30 and the 7th value of the sequence is 36. Appropriately initialize the value of 'value' which represents the 12th value in the sequence.

5) Suppose the 5th value of an arithmetic sequence is 30 and the 7th value of the sequence is 36. Appropriately initialize the value of 'sum' which represents the 8th value in the series (i.e. the sum of the first 8 values in the sequence).
