Write an expression for the sum of an even integer and the next two even integers.
Let x = the 1st integer:
x + (x+2) + (x+4)
3x + 6
:
:
The sum of i/4 of an integer, i/5 of the next integer, and i/2 of the following integer.
Let x = the 1st integer:
:
%28i%2F4%29x + %28i%2F5%29(x+1) + %28i%2F2%29(x+2)
:
Put it over a common denominator (20):
%285i%2F20%29x + %284i%2F20%29(x+1) + %2810i%2F20%29%29(x+2)
:
%285xi%2F20%29 + %284xi%2B4i%29%2F20 + %2810xi%2B20i%29%2F20%29%29
:
%285xi+%2B+4xi+%2B+4i+%2B+10xi+%2B+20i%29%2F20%29%29
:
%2819xi+%2B+24i%29%2F20%29%29
:
%28i%2819x+%2B+24%29%29%2F20%29%29
