Having trouble with this math question and cant find help in my book. Looking for an explanation, not really an answer (No, Im not trying to get someone to do my work, just help!)

This problem requires two steps.
First, layout the intial problem
5 times the first interger (x) is (or equals) 12 more (12 plus ) three times the second (3 times y)
5x=12+3y
Now that you have a problem with two unknowns we have to solve for one of the unknowns. The answer lies in the first statement.
Intergers (when consecutive are 1 number apart, if they are odd then they are two numbers apart)
Therefore:
y-x=2 ( because they are consecutive odd intergers)
or
y=x+2
Using the information we have about the value of y plug this into the first formula, and solve.
5x=12+ 3(x+2)
5x=12+3x+6
5X=18+3x
2x=18
x=9
y=11
Then of course
check your answer:
5(9) = 12+3(11)
45= 12+33
45=45
TADA!!

9 and 11 Ur 2 astonishing intergers are unknown so we could stated as them x and x+2 (that's plus 2 considering that is consecutive and its astonishing like a million and 3 or 5 and 7 that are astonishing and consecutive and are 2 numbers aside) 5 cases the 1st interger is 5x and 12 greater beneficial than thrice the 2d is 3(x+2)+12 so ur difficulty is 5x=3(x+2)+12 5x=3x+6+12 5x=3x+18 2x=18 and so x =9 (ur 1st interger) and the 2d is x+2 (x=9) so plug in for x, u get x+2 is the comparable as 9+2 that's 11.

Let the first odd integer be x. The next integer is therefore x + 2, as they are odd numbers.
The relationship between them is thus: 5x = 3(x + 2) + 12
Solve for x: 5x = 3x + 18
x = 9.
x + 2 = 11.
The integers are thus 9 and 11.

OK, let's start with what we know.
we have x and x+2 (two consecutive odd integers)
we also know that ...
5x = 3(x+2) +12
from here we can solve for x
5x = 3x + 6 +12
match like terms
5x = 3x +18
subtract 3x from each side
2x = 18
x=9
So our answer is 9 and 11.
Good luck!

take one integer as x, den other integer would be x+2(as it shud be an odd intger)
According 2 Q
5x = 12+3(x+2)
solve for x
ANSWER:9

5x = 12 + 3(x+2)
=> 2x = 18
x=9
