Question

replacement set equals to (-3,0,5,8). x+7\3 greater 2​

Answer 1

Replacement set ={−6,−3,0,3,6,9}

(1)

Truth set of the inequation are the numbers chosen from the Replacement set, that satisfies the inequation.

2x−1>9

2x>10

x>  

2

10

​  

 

x>5

So, the solution set  ={6,9}

(2)

3x+7≤1

3x≤1−7

3x≤−6

x≤  

3

−6

​  

 

x≤−2

So, the solution set  ={−6,−3}
