Question 456755
Just write an equation for what it says,
:
"find three consecutive even integers"
x, (x+2), (x+4)
:
"is such that 4 times the first decreased by the second is 12 more than the third?"
4x - (x+2) = (x+4) + 12
4x - x - 2 = x + 4 + 12
3x - 2 = x + 16
3x - x = 16 + 2
2x = 18
x + {{{18/2}}}
x = 9 is the 1st integer, but that's not even see if the solution checks out
:
4(9) - 11 = 13 + 12
36 - 11 = 25; seems to check out, perhaps a flaw in the way the problems was written.
