the sum of two numbers is 31 and their difference is 7 what are the two numbers?
its 19 and 12
its 19 and 12 cuz 12 7 numbers behind 19 12+7=19 so its 12 and 7
sorry its 12 and 19 not 12 and 7
This doesn't make no sense. This is wack.
wat
It is 19 and 12
its 12 and 19
i am confusions
12 and 19
Um...OK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
If you cauculate, the answer is 12 + 19 = 31
19 - 12 =7
So whoever answer 19 and 12, you are correct!!!!!!!
12 and 19 is the answer
Wsp the answer is 19 and 12
Lamo?
woooooooooooooooooooooooooooot?!!?!?!?!?!?!?!?!?!?!?!?!?
Also, what's the two numbers that sum up to 134, and it's the difference of 66?
This is confusing... :'>
There is know need to fight between each other BECAUSE IT IS ALL MIneeeeeeeeeeeeee !🎯🎵🎵🎵🎵🎵🎵🎵🎵
What are the two numbers
got it
This is such confusion.
that helped me
This is... :l
ha ha ha ha ha ha ha 19 and 12 (haaaaaaaaaaaaa)
19 and 12
What is the point of this
confused.
What’s the answer!
a = first number
b = second number
You have conditions:
a + b = 31 and a - b = 7
Add the two equations together to eliminate b from the system.
a + b = 31
+
a - b = 7
________
a + a + b + ( - b ) = 31 + 7
2 a + b - b = 38
2 a + 0 = 38
2 a = 38 Divide both sides by 2
a = 38 / 2 = 19
a - b = 7
19 - b = 7 Add b to both sides
19 - b + b = 7 + b
19 = 7 + b Subtract 7 to both sides
19 - 7 = 7 + b - 7
12 = b
b = 12
Proof:
a + b = 19 + 12 = 31
a - b = 19 - 12 = 7
OOOKKKAAAYYY AND?!
the key answer of this question the sum of two numbers is 31 and their difference is 7
Let x = one number and x+7 the other.
x + x + 7 = 31
Solve for x, then x+7.
