Answer:

d. x = 2

Step-by-step explanation:

Just like how you solve an equation with an equal sign, similarly, you can solve this, but with the > [greater than] sign.

 5x - 9 > -2x + 5

Take the x terms to one side and the numerical terms to the other side.

 5x + 2x > 5 + 9

Simplify.

 7x > 14

Divide both sides by 7 in order to remove the 7 with the x term.

 [tex]\frac{7}{7}[/tex] x > [tex]\frac{14}{7}[/tex]

 ∴ x > 2

We now know that x is greater than 2, so any value greater than 2 would be the answer.

The last option, which is the d option, x = 2, would be the answer. This is because x is greater than 2, not greater than or equal to 2, thus giving the answer as d.
