How do you solve #x+12<=5# or #3x-21>=0#?
First you have to - the constant (the number that doesn't multiply by x)
Then divide by the coefficient
constant = -21
coefficient is 3
Let's start with our first inequality and subtract
For our second inequality, we can add
Our last step would be to divide both sides by
Therefore our solution set for both of these inequalities is
Hope this helps!
