Question

Which of the following is not a solution to x + 2y – 3 = 0 ?

A) x = 1, y = 1 B) x = 0, y =

3

2

C) x = 3, y = 0 D) x = 1, y = –1​

Answer 1

Step-by-step explanation:

(1,-1) is not a solution to the given equation.

Answer 2

$\huge\boxed{\fcolorbox{black}{pink}{ANSWER..}}$

a) If x = 1, y = 1

x + 2y - 3 = 0

1 + 2(1) - 3 = 0

3 - 3 = 0

It is a Solution.

b) If x = 0, y = 3

x + 2y - 3 = 0

0 + 2(3) - 3 = 0

6 - 3 = 3

It is Not a Solution

c) If x = 3, y = 0

x + 2y - 3 = 0

3 + 2(0) - 3 = 0

3 - 3 = 0

It is a Solution.

d) If x = 1, y = -1

x + 2y - 3 = 0

1 + 2(-1) - 3 = 0

1 - 2 - 3 = 0

1 - 5 = - 4

It is Not a Solution.
