Question 221859: Find three consecutive even integers such that if the largest integer is subtracted from four times the smallest , the result is 6 more than twice the sum of the two smallest integers
Answer by ankor@dixie-net.com(22740)   (Show Source):
You can put this solution on YOUR website! Find three consecutive even integers
x, (x+2), (x+4)
:
the largest integer is subtracted from four times the smallest, the result
is 6 more than twice the sum of the two smallest integers.
:
4x - (x+4) = 2(x + (x+2)) + 6
Remove the brackets
4x - x - 4 = 2(2x+2) + 6
3x - 4 = 4x + 4 + 6
3x - 4 = 4x + 10
3x - 4x = 10 + 4
-x = 14
x = -14
:
-14, -12, -10 are the three integers
:
check solution in the statement:
"the largest integer is subtracted from four times the smallest, the result
is 6 more than twice the sum of the two smallest integers"
4(-14) - (-10) = 2(-14 + -12) + 6
-56 + 10 = 2(-26) + 6
-56 + 10 = -52 + 6
-46 = -46
