Question

Find all real numbers X such that 18x-9>9 or 2x-4>-10

Answer 1

So what we are going to do is the next thing:Consider 18x-9>9 1. add 9 to both sides 2. divide both sides by the coefficient of x (that is 18 in this case) Now Consider 2x-4>-10 1. Then add 4 to both sides 2. divide both sides by the coefficient of x (that is 2 in this case) The final solution would be x < 1 Hope this can fit what you are looking for

Answer 2

What you must do for this case is to solve both inequalities
 We have then:
 18x-9> 9
 We clear x:
 18x> 9 + 9
 x> 18/18
 x> 1
 2x-4> -10
 We clear x:
 2x> -10 + 4
 x> -6/2
 x> -3
 Therefore we have to
 For 2x> -10 + 4
 x belongs (-3, inf)
 For 18x> 9 + 9
 x belongs (1, inf)
The solution that is met for both inequalities is:x belongs (1, inf)
