Answer 1

The above image shows your answer.

Answer 2

Given,

Statement : The sum of the present ages of father and son is 35.

To find,

Forming a linear equation from the given statement, by using two variables.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Let,

The age of father = x years

The age of son = y years

x = first variable

y = second variable

Now, according to the data mentioned in the question,

x+y = 35

Now, this can be regarded as a linear equation because it satisfies the general form of a linear equation.

General form of linear equation : ax+by = c

Here, a = 1 , b = 1 , c = 35

Hence, the linear equation will be x+y = 35
