Question

find the value of k, if x=1, y=2is a solution of the equation 2x+3y=k

​

Answer 1

Answer:

2×1+3×2=I

2+6=k

k = 8

this is the answer

Answer 2

here K=8

Step-by-step explanation:

lets rewrite the equation as 2x+3y-k=0

if x=1 and y=2 are solutions of the equation

so at x=1 and y=2 the value of equation is 0

putting values of X and Y

2(1)+3(2)-K=0

8-K=0

K=8
