2<3x−1/6<5
add 1/6 to each part
2+1/6 < 3x < 5+1/6
13/6 < 3x < 31/6
divide by 3
13/18 < x < 31/18
add 1/6 to each part
2+1/6 < 3x < 5+1/6
13/6 < 3x < 31/6
divide by 3
13/18 < x < 31/18

oops, didn't notice the "integer" part till now.
appr .72 < x < appr 1.72
the only integer between .72 and 1.72 is the number 1
So there is one integer that satisfies the inequality
appr .72 < x < appr 1.72
the only integer between .72 and 1.72 is the number 1
So there is one integer that satisfies the inequality
