Question

The age of the elder brother is twice the age of the younger brother. Write a linear equation in two variables to represent this statement.

Give the representation of 2x+3=0 in two variables.

Answer 1

To represent the statement that the age of the elder brother is twice the age of the younger brother, we can write the equation as x = age of the younger brother and 2x = age of the elder brother. The linear equation in two variables to represent this statement is 2x - x = 0, which simplifies to x = 0. For the equation 2x + 3 = 0, there is only one variable given, so it cannot be represented in two variables.

Step-by-step explanation:

To represent the statement that the age of the elder brother is twice the age of the younger brother, we can write the equation as follows:

x = age of the younger brother

2x = age of the elder brother

The linear equation in two variables to represent this statement is: 2x - x = 0, which simplifies to x = 0.

For the equation 2x + 3 = 0, the two variables are x and y. However, since there is only one variable given in the equation, we cannot represent it in two variables.
