Question

4. What is the value of x such that 5x + 2a > 2x-a?

a. x < -a
b. x > -a
C. x < a
d. x > a

Answer 1

D: x > a

Explanation:

We have 5x - 2a > 2x-a

We can rewrite this equation by subtracting 2x on both sides, which gives:

5x - 2x -2a > 2x - 2x - a,

so 3x - 2a > a

We now add 2a on both sides, which gives:

3x -2a + 2a > a + 2a, so 3x > 3a

We nog divide both sides by 3, which gives:

3x/3 > 3a/3, so x>a

The correct answer is D
