Question 719990: Please help me solve this word problem. Using three consecutive odd integers, such that if three times the second is subtracted from the third, the difference is negative forty-eight. Find the first integer. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Using three consecutive odd integers, such that if three times the second is subtracted from the third, the difference is negative forty-eight.
Find the first integer.
Let x = the first integer
then
(x+2) = the 2nd integer
and
(x+4) = the 3rd.
:
Write an equation for exactly what it says
(x+4) - 3(x+2) = -48
x + 4 - 3x - 6 = -48
x - 3x = -48 - 4 + 6
-2x = -46
2x = 46; multiplied both sides by -1
x = 46/2
x = 23 is the first odd integer

See if that checks out.
27 - 3(25) =
27 - 75 = -48
