Answer:
Step-by-step explanation:
2/3 + 1/3 ( x+ 1) > 0
2/3 + 1x/3 + 1/3 >0
( 2 + 1x + 1 ) / 3 > 0
( 3 + 1x )/ 3 > 0
3/3 + 1x/3 >0 (3/3 is 1)
1 + 1x/3 >0 (1 will become -1 when we will change its side)
1x/3 > -1
1x > -1 × 3
x > -3
Therefore, answer is {-2 , -1}. (because -2 and -1 are bigger than -3 )
