Question

Write and solve an equation to find three consecutive odd integers whose sum is 3.

Answer 1

x = 1st odd integer
x+2 = 2nd odd integer
x+4 = 3rd odd integer

x+ x+2 + x+ 4 = 3
3x+6 = 3
3x = -3
x= -1
so -1,1,3 are consecutive odd integers

Answer 2

consecutive odd numbers are 2 apart

so they are x, x+2,x+4

the sum is 3

x+x+2+x+4=3
3x+6=3
minus 6 both sides
3x=-3
divide 3
x=-1
x+2=1
x+4=3

the numbers are -1,1,3
