Question

if x=2 and y=1 is the solution of 2x - 3x + k =0 ,then what is the value of k ?​

Answer 1

Answer:

-1

Step-by-step explanation:

if X = 2

Y = 1

Substitute the values

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

4-3+k = 0

1+k = 0

k = -1

Answer 2

we need to substitute the value of x and y in the equation...

2x - 3y + k = 0

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

4 - 3 + k = 0

1 + k = 0

k = 0 -1

k = -1

Therefore k is -1
