4. Linear Equations in Two Variables

easy

Write each of the following as an equation in two variables :

$(i)$ $x=-\,5$

$(ii)$ $y=2$

$(iii)$ $2x=3$

$(iv)$ $5y=2$

Option A

Option B

Option C

Option D

Solution

$(i)$ $x=-\,5$ can be written as $1 .x+0 .y=-\,5,$ or $1 .x+0. y+5=0$.

$(ii)$ $y=2$ can be written as $0. x+1. y=2,$ or $0.x+1. y-2=0$

$(iii)$ $2 x=3$ can be written as $2. x+0. y-3=0$

$(iv)$ $5 y=2$ can be written as $0. x+5. y-2=0$
