If (x) is an integer, how many solutions does \(-5<3x+1\le 10\) have?
Explanation opens after your attempt
D. (5)
Concept
\(-6<3x\le 9\) gives \(-2<x\le 3\), so the integers are (-1,0,1,2,3). There are (5) solutions.
Why this answer is correct
The correct answer is D. (5). \(-6<3x\le 9\) gives \(-2<x\le 3\), so the integers are (-1,0,1,2,3). There are (5) solutions.
Exam Tip
\(-6<3x\le 9\) से \(-2<x\le 3\), इसलिए पूर्णांक (-1,0,1,2,3) हैं। कुल (5) समाधान मिलते हैं।
