You can put this solution on YOUR website! find five consecutive odd integers such that the first and fifth is one less than three times the fourth
:
"find five consecutive odd integers"
x, (x+2), (x+4), (x+6), (x+8)
:
"such that the first and fifth is one less than three times the fourth"
x + (x+8) = 3(x+6) - 1
:
2x + 8 = 3x + 18 - 1
:
2x + 8 = 3x + 17
:
8 - 17 = 3x - 2x
:
-9 = x
:
The numbers: -9, -7, -5, -3, -1
;
;
Check solution:
-9 + -1 = 3(-3) - 1
-10 = -9 - 1
