Solving inequality’s:
1.Add or subtract to isolate the variable term.
2. Multiply or divide to solve for the variable. If you multiply or divide both sides by a negative number, then _______ the inequality symbol.
Solve
-5x > 20
X_____-4
1. To isolate the variable term, we can start by adding 5x to both sides: -5x + 5x > 20 + 5x. This simplifies to 0 > 20 + 5x.
2. Next, we can subtract 20 from both sides: 0 - 20 > 20 + 5x - 20. This simplifies to -20 > 5x.
3. To solve for x, we can divide both sides by 5: -20/5 > 5x/5. This simplifies to -4 > x.
Therefore, x < -4.
