Question
Solve the following system of equations graphically:
2x + 3y - 4 = 0,
3x - y + 5 = 0
2x + 3y - 4 = 0,
3x - y + 5 = 0
✓
Answer
$\text{2x}+\text{3y}-4=0$ $\Rightarrow\text{y}=\frac{4-\text{2x}}{3}$
$\text{3x}-\text{y}+5=0$ $\Rightarrow\text{y}=\text{3x}+5$
Since the two graph intersect at (-1, 2), x = -1 and y = 2
