Seven times the smaller
Taya2010 [7]

Given:

Seven times the smaller  of two consecutive even  integers  is the same as  -300 minus 4 times the  larger integer.

To find:

The integers .

Solution:

Let the smaller even integer be x.

So, larger even integer is x+2 because they are consecutive even  integers.

Seven times the smaller  integer = 7x

-300 minus 4 times the  larger integer = -300-4(x+2)

Now,

7x=-300-4(x+2)

7x=-300-4x-8

7x+4x=-308

11x=-308

Divide both sides by 11.

x=\dfrac{-308}{11}

x=-28

So, the smaller even integer is -28.

x+2=-28+2=-26

So, the larger even integer is -26.
