Question
The value of x for the inequation 3x + 15 < 5x + 13, x ∈ Z is ______.
Options
x > 1
< 1
1
≥ 1
Solution
The value of x for the inequation 3x + 15 < 5x + 13, x ∈ Z is x > 1.
Explanation:
Given 3x + 15 < 5x + 13
`\implies` 15 – 13 < 5x – 3x
`\implies` 2 < 2x
`\implies` 2x > 2
`\implies` x > 1
