Question

Find three consecutive odd integers such that the sum of the largest and twice the smallest is 25,

If x represents the smallest integer, then which equation could be used to solve the problem?
2x+X+2=25
2x + x +45 25
2x + 2x + 425

Answer 1

Explanation:

If the smallest integer is x, the next odd number would be x + 2, and the largest would be x + 4. The sum of the largest (x+4) and twice the smallest (2x) is 25. The equation for that would be (x+4)+2x=25 which is 3x + 4 = 25. Not sure how far you have to go with it. But that equation could be solved for x.
