\left. \begin{array} { l } { \text { a- } \frac { 1 } { 2 } x - \frac { 2 } { 3 } y + 2 = 0 \quad c - 3 x + 2 y + 8 = 0 } \\ { b - \frac { 4 } { 5 } x + \frac { 1 } { 5 } y + 1 = 0 \quad d - 4 x + 7 y - 9 = 0 } \end{array} \right.
Evaluate (complex solution)
-\frac{x}{2}-\frac{2y}{3}+a+2=8+2y-3x\text{ and }8+2y-3x=0,\ \frac{y}{5}-\frac{4x}{5}+b+1=-4x+7y-9\text{ and }-4x+7y-9=0
Solve for x
x = \frac{74}{13} = 5\frac{9}{13} \approx 5.692307692
y=\frac{59}{13}\text{ and }a=\frac{151}{39}\text{ and }b=\frac{172}{65}
Solve for y
y = \frac{59}{13} = 4\frac{7}{13} = 4.538461538461538
x=\frac{74}{13}\text{ and }a=\frac{151}{39}\text{ and }b=\frac{172}{65}
