The pair of linear equations $5x+4y=20$ and $10x+8y=16$, will have no solution. why?
Given: The pair of linear equations $5x+4y=20$ and $10x+8y=16$ will have no solution.
To do: To explain the reason why the given pair of linear equation has no solution.
Solution:
Here, $a_1=5,\ b_1=4,\ c_1=20$ and $a_2=10,\ b_2=8,\ c_2=16$.
$\frac{a_1}{a_2}=\frac{5}{10}=\frac{1}{2}$
$\frac{b_1}{b_2}=\frac{4}{8}=\frac{1}{2}$
$\frac{c_1}{c_2}=\frac{20}{16}=\frac{5}{4}$
Therefore, we find that $\frac{a_1}{a_2}=\frac{b_1}{b_2}≠\frac{c_1}{c_2}$
Thus, There is no solution for the given pair of equation.
