Question

Solve the inequation:
5x + 7 > 4 – 2x

Answer 1

5x + 7 > 4 – 2x
Adding 2x on both sides, we get
7x + 7 > 4
Subtracting 7 from both sides, we get
7x > – 3
Dividing by 7 on both sides, we get
∴ `"x" > -3/7`
i.e., x takes all real values greater than `(-3)/7`
∴ The solution set is unbounded open interval `((-3)/7,∞)`
