# Math Help - Solving two inequalities with three variables

1. ## Solving two inequalities with three variables

Hi everyone,

How can I solve two inequalities with three variables like the following:
x+y+0.94z>=0.9
x+y+0.94z<=1

I need it to be something like x+y+0.94=(some value).

Maybe using constraints?

Let $t = x+y+0.94z$. Then $0.9\le t \le 1$ is an inequality in one variable. I don't understand what you are trying to do.
