Question

if x=2, y=-1 is the solution of the equation ax-y=5, find the value of a. Also find tow more solutions of the equation.
​

Answer 1

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.
