what is the solution set for 2x + 5 > 7? a x > -1 b x < 3 c x < -2 d x > 1
what is the solution set for 2x + 5 > 7? a x > -1 b x < 3 c x < -2 d x > 1
Answer
Explanation:
Step1: Subtract 5 from both sides
$$ \begin{align*} 2x+5-5&>7 - 5\ 2x&>2 \end{align*} $$
Step2: Divide both sides by 2
$$ \begin{align*} \frac{2x}{2}&>\frac{2}{2}\ x&>1 \end{align*} $$
