The problem seems confusing is it supposed to say y=?
Answer:
4 x + 4 y = 1 , 6 x − y = 1 2 x + y = − 2 , x + 2 y = 2 x + 2 y = 4 , x − y = − 3

Answer:
93,675
Step-by-step explanation:
We see that the given sequence is an arithmetic sequence with first term 997, common difference -5, and last term 252.
The number of terms in the sequence (n) can be found from the formula for the n-th term:
an = a1 +d(n -1)
(an -an)/d +1 = n
(252 -997)/(-5) +1 = n = 150
The sum of these terms is the average of the first and last terms, multiplied by the number of terms:
S150 = (997 +252)/2·150 = 93,675
The sequence sum is 93,675.
