Answer:
x∈ (-1, ∞)
Step-by-step explanation:
<u>Solution of the inequality:</u>
- −2(3x − 1) < 8 ⇒ Divide both sides by -2, this will change inequality
sign to opposite
- 3x - 1 > -4 ⇒ add 1 to both sides
- 3x > -3 ⇒ divide both sides by 3
- x > -1 ⇒ answer
- x∈ (-1, ∞) ⇒ answer as set
So 1 would be 5r+20 and then the second one would be
