Answer:
2 and 3
Step-by-step explanation:
Let x and y represent the first and second numbers, respectively.
3x +3y = 15
4x +2y = 14
Dividing the equations by common factors, we can rewrite them to standard form:
x + y = 5
2x + y = 7
Subtracting the first equation from the second gives ...
(2x +y) -(x +y) = (7) -(5)
x = 2
Using either equation to find y, we have also ...
y = 3
The two numbers are 2 and 3.

Answer:
17,18
Step-by-step explanation:
let the smaller integer be "a" and the larger be "b"
Then 2b = 3a -15 ........................equ 1
but they are consecutive integers, b= a+1 ; substitute b into equ 1,thus,
2(a+1) = 3a - 15
2a + 2 = 3a-15
collect like terms,
2+15 =3a-2a
17 = a
b= a+1
b = 17+1
b=18.
The integers are 17,18
