Solve the following system of equations: x - 2y = 5, 2x - 4y = 10

Solution:

Given, the system of equations is

x - 2y = 5 --- (1)

2x - 4y = 10 --- (2)

We have to solve the system of equations.

Dividing (2) by 2,

x - 2y = 5 which is same as equation (1)

Thus, the system will have many infinite solutions.

For a system of equation having infinite solution following condition holds:

\(\frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}}=\frac{c_{1}}{c_{2}}\)

Here, a₁ = 1, b₁ = -2, c₁ = 5

a₂ = 2, b₂ = -4, c₂ = 10

Now, \(\\\frac{1}{2}=\frac{-2}{-4}=\frac{5}{10}\\\frac{1}{2}=\frac{1}{2}=\frac{1}{2}\)

Therefore, \(\\\frac{3}{6}=\frac{-2}{-4}=\frac{6}{12}=\frac{1}{2}\).

Solve the following system of equations: x - 2y = 5, 2x - 4y = 10

Summary:

The system of equations: x - 2y = 5, 2x - 4y = 10 will have many infinite solutions.
