Respuesta :
Isolate the variable by dividing each side by factors that don't contain the variable.
Inequality Form:
x < − 3
Interval Notation:
( − ∞ , − 3 )
Answer:
x ∠ -3
Step-by-step explanation:
To solve this inequalities, we have to follow the steps below
- open the bracket
- collect like term
- subtract and then divide both-side so that we can be left with just the variable
9(2x +1) < 9x - 18
opening the bracket, equation becomes;
18x + 9 < 9x - 18
collect like terms, numbers with x variables on the left hand side and number standing alone on the right hand side of the inequality
18x - 9x < -18-9
9x < -27
Divide both-side of the equation by 9
9x/9 < -27/9
x < -3
