Question

17. Find the value of k, if x = 2, y = 1 is a solution of the equation 2x + 3y = k. Express y in terms of x and
find the value of y when x = -1.​

Answer 1

Answer:

x=2 , y = 1

Step-by-step explanation:

2×2 + 3×1 = k

4+3=k

7=k

value of k is 7

x+k=y

(-1)× 7=y

-1×7 =y

-7=y

Answer 2

Step-by-step explanation:

K =5

So

2x+3y=5

Y =7/3
