<span>the sum of three consecutive odd integers is 69. Find the integers. ------------- 1st: 2x-1 2nd: 2x+1 3rd: 2x+3 --------------------- Equation:</span>2x-1 + 2x+1 + 2x+3 = 69<span> </span><span>6x + 3 = 69 2x + 1 = 23 ----------------- So 2x-1 = 21 And 2x+3 = 25
</span><span>let: x be the first odd integer x + 2 be the 2nd odd integer x + 4 be the 3rd odd integer solution: 1st odd integer + 2nd odd integer + 3rd odd integer = 69 x + (x+2) + (x+4)= 69 </span> <span>3x + 6 = 69 3x = 69 - 6 3x = 63 (dividing both sides by three) x = 21 _______________________________________ x=21 x+2=23 x+4=25 therefore, the 1st integer is 21, the 2nd is 23 and the 3rd is 25..</span>
