To solve inequality.
Answer to Problem 5.4.2.3P
Solution set: {x|x>-1.6 and x<4}
Interval notation: (-1.6,4)
Explanation of Solution
Given information:
Inequality
Calculation:
So,
On resolving,
Adding 1 in all sides of compound inequality,
On solving,
Dividing by 2 all sides of compound inequality
On solving,
Separating compound inequality by "and"
For
Adding 0.25x both side
On solving,
Divide by 1.25 both sides,
On solving,
For
Subtracting 0.25x both sides
On solving,
Divide by 0.75 both sides
On solving,
Hence, Solution set: {x|x>-1.6 and x<4}
The graph of inequality is given below
Interval notation: (-1.6, 4)
