Question

7 + z < 3

Can someone help me solve this inequality please?

Answer 1

The answer is z < -4

To find the answer to an inequality, you treat it just like an equation and try to get the variable by itself. So, to do this we subtract 7 from both sides and we get z < -4

Hope this helped!!! :)

Answer 2

7 + z < 3

You solve this the same way you would any other algebraic expression such as..

7 + x = 3.

So, just subtract the seven from the three and you have your answer!

7 + z < 3

7 + z - 7 < 3 - 7

z < -4
