ক)
x>9খ)
x< 13গ)
x<7ঘ)
None of theseExplanation
(4x-7) < (2x+13) 4x - 2x < 13+7 2x < 20 x < 10 Now, x>9 would allow x to be 11 or higher, which it cannot be. x<13 would also allow x to be 11 or higher, which it cannot be. but x<7 has no values of x in it, which cannot be expressed in the original expression "x<10"Related questions
