three consecutive even integers are x, x+2, x+4. Their sum is x+x+2+x+4 = 3x+6.
a. 3x%2B6=156,
3x+=+150,
x+=+50. Therefore the consecutive even integers are 50, 52, 54.
b. 3x%2B6=258,
3x+=+252,
x+=+84. Therefore the consecutive even integers are 84, 86, 88.
c. 3x%2B6=-60,
3x+=+-66,
x+=+-22. Therefore the consecutive even integers are -22, -20, -18.
