1.	If x=2 y= 1 is a solution of the equation 2c + 3y I find the value of k
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=7y= 37 At y=0,2x+3(0)=7x= 27 ∴(0, 37 ) and ( 27 ,0) are two more SOLUTIONS of resultant equations.

If x=2 y= 1 is a solution of the equation 2c + 3y I find the value of k

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=7y= 37

At y=0,2x+3(0)=7x= 27 ∴(0, 37 ) and ( 27 ,0) are two more SOLUTIONS of resultant equations.
