Question

An inequality has g=1 as a solution, but g=2 is not a solution . What is the inequality?

Answer 1

We know 1 is a solution, but 2 is not.
We also know that 1 is 'less than' 2
Key words: less than
That means are inequality will be: g<2
Now if we plug 2 in for g it will say:2<2 
We know two is not less than two, two is equal to two.
Now let's plug 1 in for g: 1<2
So we know 1 is less than 2. Therefore, this inequality is true.
Hope that helped :)
