i’m a kid ))))))))))))
im 9 yrs old

from united states university

ok guess my name says it all.. correct answer is
y is dad, x is son
1.
y+5 = 4(x-1) —- 1
y+5 = 3(x+6) —- 2
Solving it gives
dad = 79, son = 22
2
y+3=4(x+2) —– 1
y+3=5x
Solving it gives
dad = 37 , son = 8
not gonna write how i will ans this )

y+3=5x —— 2

Solving it gives
dad = 37 , son = 8

not gonna write how it’s solved i’m pretty sure u can do that..

H’okay… ages are 8 and 37 respectively in corrected version (http://www.qgmindpolice.com/wp-content/uploads/2009/03/2009-01-15-mathdad2.png). The world is at peace again finally. Poor cartoonist, haunted evermore due to the internet’s ability to link to superseded material. lolz

(corrected version math for lazy people:
kid’s age is x
dad’s age is y

y + 3 = 4(x + 2)
y + 3 = 5x
5x = 4x + 8
x = 8
y = 37

Jm, this is a two variable equation because you have to find x and y, you just skipped the first step/did it in your head (making both equations equal to y so you can drop a variable), but either way yours is wrong because you are saying 3x+6 when it should be 3(x+6) +5

In most of the equations with the wrong answers people are only putting + 5 in the first equation when it needs to be in both.
4x-4=y+5
3x+18=y+5

but it’s kind of confusing because if they’d bothered to check their answers they would have seen that they were wrong. I mean didn’t every high school math teacher ever tell you to go back and check all your answers?

and for the record… this is MATH! There are not “several” correct answers. There are not “ways to look at it” there may be different ways to solve or write an equation but if you aren’t getting the same answer then your equation is wrong or solved incorrectly.

were talking about 1 age here (the kids age). with that, you get what the age of the dad is by plugging in the kids age into the formula. i dont know why you guys had to put in 2 variables.

heres what i got.

4(x-1)+5 = 3x + 6
4x -4 +5 = 3x + 6
4x +1 = 3x + 6
x = 5

plugging in the variable.

4 ( 5 -1 ) + 5 = 21
and
3(5) + 6 = 21.
