Question

Find a value for a so that each of the following equations may have x=1, y=1
as a solution:
(i)3x+ay = 6 (iii)x-y = a
(ii)ax-2y = 10 (iv)5x+3y = a

Answer 1

Answer:

3xy

Step-by-step explanation:

3x+ay=6

=3x-6y=a

=3xy=a

Answer 2

Answer:

(i)3*1+a*1=3a+1a

(ii)x-y=a

(iii)ax-2y=10=a*1-2*1=10

(iv)5x+3y=a=5*1+3*1=a
