(B) Given equations are:
$2x - 2y - 2 = 0$ (Equation $1$)
$4x - 4y - 5 = 0$ (Equation $2$)
Comparing these with the standard form $a_1x + b_1y + c_1 = 0$ and $a_2x + b_2y + c_2 = 0$,we get:
$a_1 = 2, b_1 = -2, c_1 = -2$
$a_2 = 4, b_2 = -4, c_2 = -5$
Now,find the ratios:
$\frac{a_1}{a_2} = \frac{2}{4} = \frac{1}{2}$
$\frac{b_1}{b_2} = \frac{-2}{-4} = \frac{1}{2}$
$\frac{c_1}{c_2} = \frac{-2}{-5} = \frac{2}{5}$
Since $\frac{a_1}{a_2} = \frac{b_1}{b_2} \neq \frac{c_1}{c_2}$,the lines are parallel to each other.
Therefore,the pair of linear equations is inconsistent and has no solution.
