The numbers whose sum is 32 in which one number is 3 times the other is 8 and 24 respectively.
<h3>Equation of the unknown</h3>
Let
- x = one of the unknowns
- 3x = second unknown
x + 3x = 32
4x = 32
x = 32/4
x = 8
So,
3x = second unknown
= 3(8)
= 24
Check:
x + 3x = 32
8 + 24 = 32

Hey There!
One of the numbers she might be thinking of could be 1,298, because it rounds to 1,300 in the nearest hundreds, and for the nearest tens. Remember, when a number is greater than 5 you round it to the nearest ten. Same rule applies for the hundreds, but the number has to be in the tens place instead of the ones place.

1)4x-7=2x+9
Subtract 2x
2x-7= 9
Add 7
2x=16
X= 8
2(8)+9=25
(8,25)
X+y=10
-X-2y=-14
-y= -4
Y=4
X+4=10
X=6
(6,4)
