Solving inequalities is almost the same as solving equalities for basic cases. Only thing you've to watch out for is signs.
For example, in 2x + 3 > 5,
We may subtract 3 from both sides,
2x > 2
Hence, by dividing both sides by 2, we get x>1.

The inequality sign changes on multiplying with (-)
For example, 2 < 6
But, -2 > -6

And when you interchange a fraction
E.g. 3/4 > 2/3
But, 4/3 < 3/2

You can now solve these of your own
