Given the inequality expression;
- 3( x - 4) < - 12
you are to evalauate the value of x in the expression;
Step 1: Open the parenthesis
- 3( x - 4) < - 12
-3x+12 < - 12
Step 2: Subtract 12 from both sides;
-3x+12-12 < -12-12
-3x < -24
Step 3: Divide both sides by -3;
-3x/-3 < -24/-3
x > 8 (note the reverse in the inequality sign. This is because I divided both sided of the ineequality by a negative value)
The solution is x> 8
