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
