Question

The solution to -2x/3+7<15 is the set

1. x>-12
2. x<-6
3. x>33
4. x<-10

Answer 1

1) x > -12

Explanation:

first, subtract 7 from each side of the inequality to get:

-2/3x < 8

multiply each side by the reciprocal of -2/3 which is -3/2 to get:

x > -24/2

notice the symbol has been reversed because that is the rule whenever you multiply or divide an equality be a negative value

simplified, answer is x > -12
