Question

lie
Find the value ofk, ifx=2, y=1 is a solution of the equation 2x+3y=k. Find two more
solutions of the resultant equation.​

Answer 1

Step-by-step explanation:

ANSWER

Given equation, 2x+3y=k

x=2,y=1 is solution of resultant equation.

2(2)+3(1)=k

∴k=7

∴ Resultant equation is 2x+3y=7

At x=0,2(0)+3y=7

y=

3

7

At y=0,2x+3(0)=7

x=

2

7

∴(0,

3

7

) and (

2

7

,0) are two more solutions of resultant equations.
