Answer:
[tex]x > -9[/tex]
Step-by-step explanation:
Step 1: Make an inequality
[tex]-3x - 7 < 20[/tex]
Step 2: Add 7 to both sides
[tex]-3x - 7 + 7 < 20 + 7[/tex]
[tex]-3x < 27[/tex]
Step 3: Divide both sides by -3
[tex]-3x / -3 < 27 / -3[/tex]
Since you divide by a negative, you must flip the sign.
[tex]-3x / -3 < 27 / -3[/tex]
[tex]x > -27/3[/tex]
[tex]x > -9[/tex]
Answer: [tex]x > -9[/tex]
I'll teach and give you the answer to your problem -3x-7 > 20.
-------------------------------------------
Add seven to both sides:
-3x-7+7<20+7
Simplify:
-3x < 27
Multiply both sides by -1 (reverse the inequality):
(-3x)(-1)>27(-1)
Simplify:
3x>-27
Divide both sides by 3:
3x/3 > -27/3
Simplify:
x > -9
Your Answer Is x > -9
