If (7-4x>19), which solution for (x) is correct?यदि (7-4x>19) है तो (x) का सही हल कौन सा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x<-3)(x<-3)
From (7-4x>19), we get (-4x>12), so (x<-3). The inequality sign reverses when dividing by a negative number.(7-4x>19) से (-4x>12) और (x<-3) मिलता है। ऋणात्मक संख्या से भाग देते समय असमता का चिन्ह पलटता है।
