Given :
- x = 2
- y = 3
To Find :
- x + 3y = 11
- 5x - 2y - 4 = 0
Solution :
We will substitute the given values of x and y in the equation to confirm the answer.
a)
⠀⟶⠀x + 3y = 11
⠀⟶⠀2 + 3(3) = 11
⠀⟶⠀2 + 9 = 11
⠀⟶⠀11 = 11⠀⠀⠀⠀⠀[Hence Confirmed]
___________________
b)
⠀⟶⠀5x - 2y - 4 = 0
⠀⟶⠀5(2) - 2(3) - 4 = 0
⠀⟶⠀10 - 6 - 4 = 0
⠀⟶⠀4 - 4 = 0⠀⠀⠀⠀⠀
⠀⟶⠀0 = 0⠀⠀⠀⠀⠀[Hence Confirmed]
Thus, the value of x and y satisfy the equation.

Answer :
- 11 = 11
- 0 = 0
Given :
- x = 2 , y = 3 is a solution for linear equation x + 3y = 11 and 5x - 2y = 4
To find :
- x + 3y = 11
- 5x - 2y - 4
Solution:
Given , x = 2 and y = 3
(1) x + 3y = 11
》x + 3y = 11
》2 + 3(3) = 11
》2 + 9 = 11
》 11 = 11
(2) 5x -2y - 4 = 0
》5x- 2y - 4 = 0
》5(2) - 2(3) - 4 = 0
》10 - 6 - 4 = 0
》4 - 4 = 0
》0 = 0
Hence Verified
More Explanation :
- A linear equation is nothing but in variable x is an equation so that can be written in the form ax + b = 0
- Where , a and b are real numbers then a is not equal to zero
