Question

what will be the value of x for the inequation -2x+1 more than equals too 9 x e {-1,-2,-3,-4}​

Answer 1

Answer:

Given inequation, x−3<2x−1

⇒x−2x<−1+3

⇒−x<2

⇒x>−2[On multip;ying by −1, the inequality sign reverses]

But, x∈{1,2,3,4,5,6,7,9}

Hence, the solution set is {1,2,3,4,5,6,7,9}.

Answer 2

-2x>/= 9

=> x>/= 9/-2

=> x>/= -9/2

so solution set of x

= {-4,-3,-2,-1,0,1,2,3...}
