Draw the graph of each of the following linear equations in two variables:
(i) `x+y=4` (ii) `x-y=2`
(iii) `y=3x` (iv) `3=2x+y`

Explanation

To draw the graphs of the given linear equations in two variables, we will follow a systematic approach for each equation.

### (i) For the equation \( x + y = 4 \):

1. **Create a table of values**:
- Choose values for \( x \) and calculate corresponding \( y \).
- Let \( x = 0 \):
\[
