You can put this solution on YOUR website! one half of a certain even integer plus one fifth of the next consecutive even integer equals 48. Find the two integers.
-------------------
NOte: All even integers are multiples of 2.
That is what makes them even.
-----
1st even integer: 2x
2nd: next consecutive even integer 2x+2
----------------
Equation:
(1/2)(2x) + (1/5)(2x+2) = 48
x + (2/5)x + (2/5) = 48
(7/5)x = 240/5
---
7x = 240
x = 240/7
---
2x is not an even integer
2x+2 is not an even integer
----
Please check the problem statement.

You can put this solution on YOUR website! HI,
*Note: consecutive even integers differ by 2
Let x and (x+2) represent the two integers
.
Write as You Read
.
simplify and solve
Mutiplying each term on both sides of equation by 10
.
x = 68
(x=2) = 70
.
check Your answer
34 + 14 = 48
