Question

Which of the following is a solution of the equation 2x 3y 13?

Answer 1

Explanation:

Given equations are

2x+3y=13 ....(1)

4x+y=11 .....(2)

multiply the equation (2) by 3, we get

⇒12x+3y=33 .....(3)

Subtract equation (1) from (3) to eliminate y, we get

12x+3y=33

2x+3y=13

− − −

10x=20

⇒x=2

Put this value in equation (1), we get

⇒2(2)+3y=13

⇒4+3y=13

⇒3y=9

⇒y=3

∴ the solution is x=2,y=3.
