Answer:
21
Step-by-step explanation:
Let the smallest of the numbers be N
The other two numbers (consecutive) would be written as (n + 2), (n + 4)
Expressing these as an equation gives : (n) + (n+2) + (n+4) = 69
opening the bracket and collecting like terms, we have:
n+n+n+2+4=69
3n + 6 = 69
3n = 69 - 6
3n = 63
Dividing both sides by 3 or making n the subject formular, we get:
n = 63/3
n = 21.
Note, the other numbers are: 21, 23, and 25
They are all odd numbers
Their sum equals to 69

Why do people utilise coordinate geometry?
For the purpose of connecting algebra and geometry with the aid of line and curve graphs, coordinate geometry is necessary. Finding points on a plane is a crucial component of mathematics. It also has a number of uses in other scientific fields such dimensional geometry, calculus, and trigonometry. Use y=-2x in place of x in the first equation:
5x - 9(-2x) = -46
Simplify and find x's value:
5x + 18x = -46
23x = -46
x = -2
We can use the second equation to get y now that we know the value of x:
y = -2x = -2(-2) = 4
