Solve -2x<9. x> ____
-2x<9
x < 9/-2
x < -4.5
ooops. negative multiplication changes direction:
-2x < 9
x > 9/-2
x > -4.5
To solve the inequality -2x < 9, we need to isolate the variable x. Let's go step by step:
Step 1: Divide both sides of the inequality by -2. Remember that when dividing an inequality by a negative number, the inequality sign flips.
(-2x) / -2 > 9 / -2
Simplifying, we have:
x > -4.5
So, the answer to the inequality -2x < 9 is x > -4.5.
