Answer:

2x+1 + 2x+3 + 2x+5 = -3

Explanation:

2x+1 - the first odd integer

2 x+1 + 2 = 2x+3 - the next odd integer consecutive to 2x+1

2x+3+2 = 2x+5 - the odd integer consecutive to 2x+3 (the third consecutive odd integer)

2x+1 + 2x+3 + 2x+5 - the sum of three consecutive odd integers

therefore the equation:

2x+1 + 2x+3 + 2x+5 = -3

6x + 9 = -3

6x = -12

x = -2

2x+1=2(-2)+1=-3

2x+3=2(-2)+3=-1

2x+5=2(-2)+5=1

the three consecutive odd integers whose sum is -3 are: -3,-1,1
