Question

Give the geometrical representation of 3x+7=0 as an equation in i) One variable ii) Two variables

Answer 1

Answer:

please mark as brainliest so that you would get points

Explanation:

(a) In one variable,

3x+7=0

⇒3x= —7………….(i)

Equation (i) is an equation of one variable i.e., 'x'.

(b) In two variables,

3x+7=0

⇒3x=−7

⇒3x+0y=−7 ……….(ii)

Equation (ii) is represented as an equation of two variables i.e., 'x' and 'y'.
