# how do you solve linear inequations

**Question description**

I don't know how to solve and graph a linear inequation. I can't key in the formula, because I can't make the sub 1 or subscripts that represent the variable. The problem says: Minimize Z=8x (sub1) + 6x (sub2) subject to: 4x (sub1)+2x (sub2) >= 20, -6x (sub1) +4x (sub2) <= 12, X (sub1) + X (sub2) >= 6, X (sub1), X (sub2) >=0
