## 6.1 Revision for Linear Systems

#### Linear Literal Equation Systems

- In previous years, you are already equipped with the skills to solve simple linear equations like 4 y-\frac{(3 y+4)}{2}+\frac{1}{3}=\frac{5(4-y)}{3}, including their corresponding worded problems. The skills learnt are crucial and will be applied in the topics explored in this course.

- A literal equation in x is an equation whose solution will be expressed in terms of pronumerals rather than numbers.

In simpler terms, instead of solving

2x+5=7

instead you will be dealing with

ax+b=c
