Question

15. Prove that x = 1, y = 1 as well as x=2, y = 5 is a solution of 4x - y - 3 = 0.​

Answer 1

Answer:

For x = 1, y = 1

4×1-1-3

= 3-3

=0

For x=2, y = 5

4×2-5-3

=8-5-3

=3-3

=0

Hence proved

Answer 2

Answer:

first putting the value of x and y in given equation

• When x=1 and y=1
• 4 × 1 - 1 - 3 = 4 - 4 =0........equ.1
• now , when x=2 and y=5
• 4 × 2 - 5 -3 = 8 - 8 = 0.....equ.2
• from equation 1st and 2nd we get zero hence proved....
