Given:
A linear equation in two variables 3x + y = 7.
To Find:
The value of x if y is equal to 1.
Solution:
1. The given linear equation is 3x + y = 7.
2. The value of x if y = 1 can be calculated using elementary mathematical calculations.
=> 3x + y = 7, ( Substitute the value of y as 1 ),
=> 3x + 1 = 7,
=> 3x = 7 - 1,
=> 3x = 6,
=> x = 6/3,
=> x = 2.
3. The value of x is 2.
Therefore, the value of x is 2.
