You can put this solution on YOUR website! Just write an expression or equation for what it says:
"Find three consecutive even integers"
x, (x+2), (x+4)
:
" such that three times the middle integer is six more than the sum of the first and third."
3(x+2) = 6 + x + (x+4)
:
3x + 6 = 2x + 10
:
3x - 2x = 10 - 6
:
x = 4 is the 1st integer, then 6, 8 are the next two

Check solution in the statement:
"three times the middle integer is six more than the sum of the first and third."
3(6) = 6 + 4 + 8; confirms our solution
:
Not that hard, right?
