Question

What is the solution to the inequality?

7x+18>−3

A.​ ​ x<−3 ​ ​

B.​ x>3 ​

C.​ x<3 ​

D.​ x>−3 ​

Answer 1

Hi there!

Below are the steps to solving the inequality, but there's not a lot.

1) Subtract 18 from both sides

7x + 18 - 18 > -3 - 18
7x > -21

2) Divide both sides by 7

7x/7 > -21/7

This gives you x > -3, so the correct answer is choice D.
If you're in doubt of this you can substitute the x > -3 for the x in the equation and see what you get. It's pretty simple.

Hope this helps!

Answer 2

7x + 18 > -3

Subtract 18 from both sides,
7x > -21

Divide from 7,
x > -3

In short, Your Answer would be Option D

Hope this helps!
