what is the solution set for 31 > -5 + 4x? a x < -9 b x > -9 c x > 9 d x < 9
what is the solution set for 31 > -5 + 4x? a x < -9 b x > -9 c x > 9 d x < 9
Answer
Explanation:
Step1: Add 5 to both sides
$$31 + 5> - 5+4x + 5$$ $$36>4x$$
Step2: Divide both sides by 4
$$\frac{36}{4}>\frac{4x}{4}$$ $$9 > x$$
Answer:
D. (x < 9)
