Question

1A) Select the correct alternative from those provided in the bracket:
If x = 2, y = 1 is the solution of the equation 2x + 3y = k then the value
of k is
(5, 7, 8, 10 )

Answer 1

Answer:

as X=2,y=1

then,

(2*2)+(3*1)

=4+3

=7

Answer 2

Step-by-step explanation:

2x+3y=k

x=2 and y = 1 (given )

now put the value of x and y in the above equation

after putting the value

we get,

2×2+3×1=K

4+3= K

7 = K

hence K is equal to 7

so answer is 7
