To solve the inequality, we will isolate the x variable.
-4x - 9 < - 25
First, add 9 to both sides of the inequality:
-4x - 9 + 9 < - 25 + 9
Simplifying, we get:
-4x < -16
Next, divide both sides of the inequality by -4. Since we are dividing by a negative number, we need to reverse the inequality symbol:
x > (-16)/(-4)
Simplifying, we get:
x > 4
Therefore, the solution in set-builder notation is:
{x | x > 4}
Solve the inequality. Write the solution in set-builder notation.
-4x -9 < - 25
