Write the number of solutions of the following pair of liner equations

Open in App

Solution

$x + 2 y - 8 = 0, 2 x + 4 y = 16$
$\frac{a_{1}}{a_{2}} = \frac{1}{2}, \frac{b_{1}}{b_{2}} = \frac{2}{4} = \frac{1}{2}, \frac{c_{1}}{c_{2}} = \frac{- 8}{- 16} = \frac{1}{2}$
$∴ \frac{a_{1}}{a_{2}} = \frac{b_{1}}{b_{2}} = \frac{c_{1}}{c_{2}}$
The pair of linear equations has infinite many solution

(2 m - 1) x + 3 y = 5; 3 x + (n - 1) y = 2

x - y = 3, 3 x - 3 y + = 9

\frac{3 x}{2} - \frac{5 y}{3} = - 2

\frac{x}{3} + \frac{y}{2} = \frac{13}{2}
