Question

Solve $2x+3=5x+6$ & represent it as

i) One variable

ii) Two variable

Answer 1

Given, $2x+3=5x+6$
$3-6=5x-2x$
$3x=-3$
$x=-1$

1) In one variable

$2x+3=5x+6\to 1$

$5x-2x+6-3=0$
$3x+3=0$
$x+1=0$

$x+1=0$ is the equation in one variable

2)In two variable

$2x+3=5x+6\to 1$

Let, consider the whole equation is equal to y

$y=5x-2x+6-3$
$y=3x+3$
$3x-y+3=0$
$3x-y+3=0$ is the equation in two variables.
