The five integers are: x x+2 x+4 x+6 x+8
Mertsj
  • Mertsj
The sum of the two smallest is x + x+2 or 2x+2
Mertsj
  • Mertsj
That sum, 2x+2 is 50 less than the sum of the other three. The sum of the other three is 3x+18 So we have 2x+2=3x+18-50

x=-34
Mertsj
  • Mertsj
I got 34 but that is not an odd integer.
Mertsj
  • Mertsj
Are you sure the problem said odd?
anonymous
  • anonymous
my mistake it says even
Mertsj
  • Mertsj
Did you find you mistake in getting -34?
anonymous
  • anonymous
3x+18-50=2x+2
anonymous
  • anonymous
3x+34=2x
anonymous
  • anonymous
34=-1x

x=-34
Mertsj
  • Mertsj
3x+18-50=2x+2 3x-32 = 2x=2 3x=2x+34 x=34
anonymous
  • anonymous
you didn't move the two from the other side cuz 18-50 is -32 then plus 2 is -30

wait I see what you did

A man is currently 26yrs older than his son. 12yrs before the current time, the man will be twice as old as his son. what is the current age of the father?
Mertsj
  • Mertsj
x= son's age now x+26 = man's age now x-12= son's age 12 years ago x+26-12=man's age 12 years ago=x+14 x+14=2(x-12)

x=52
Mertsj
  • Mertsj
i got 38
anonymous
  • anonymous
okay what did I do wrong?
anonymous
  • anonymous
2x+52=2x
anonymous
  • anonymous
28+24=52
Mertsj
  • Mertsj
\[x+14=2x-24\]
anonymous
  • anonymous
isn't there two x+14? or just that one?
Mertsj

Mertsj
  • Mertsj
So the son is 38, the father is 38+26 or 64 Twelve years the son was 26 and the father was 52 And 52 is twice 26 just like the problem says.
anonymous
  • anonymous
wait soo I got the right answer to begin with?
Mertsj
  • Mertsj
If you said the son is 38 you did. Is that what you said?
anonymous
  • anonymous
I said the dad is 52
Mertsj
  • Mertsj
Is 38+26 equal to 52?
anonymous
  • anonymous
guess I was wrong
Mertsj
  • Mertsj
12 years ago the father was 52. He is now 64 and the problem asks how old the father is now.
anonymous
  • anonymous
of course

How old is her mother right now?
anonymous
  • anonymous

anonymous
  • anonymous
x+21=x-2/3-11+x
Mertsj
  • Mertsj
x= daughter's age now x+21=mother's age now x-11=daughter's age 11 years ago. x+21-11=x+10 = mother's age 11 years ago. x-11=2/3(x+10)
Mertsj
  • Mertsj
Solve it.

x=55
