You can solve linear silmultaneous equations by elimination or substitution

you can use the substitution method to solve simultaneous equations , where one equation is linear and the other is quadratic. You usually start by finding an expression for x or y from the linear equation.

when you multiply or divide an inequality by a negetiv number, you need to change the inequality sign to its opposite

to solve a quadratic inequality you :

- solve the corressponding quadratic equation
- sketch the graph of the quadratic function
- use your sketch to fiind the required set of values.
- look back in pride -- you just did matsh ! *round of appaluse*
