Answer 1

Answer:

(i) In one variable

Given equation is 2x+9=0

⇒2x=−9

⇒x=

2

−9

=−4.5

(ii) Given equation is 2x+9=0

⇒2x+0y+9=0

⇒2x=−9

⇒x=

2

−9

=−4.5

It is line parallel to y-axis at a negative distance.

Two points lying it are the points A(−4.5,0),B(−4.5,2).

solution

Answer 2

2x + 9 = 0

2x = 0 - 9

2x = -9

x = -9
