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.
