Question

The pair of linear equations

\frac{3 x}{2} + \frac{5 y}{3} = 7

and

9 x + 10 y = 14

is

Solution

1

\frac{3 x}{2} + \frac{5 y}{3} = 7 \Rightarrow 9 x + 10 y = 42

and

9 x + 10 y = 14

. Here

\frac{a _{1}}{a _{2}} = \frac{b _{1}}{b _{2}} \neq = \frac{c _{1}}{c _{2}}

, so the system is inconsistent.
