It was 10 o' clock in the night. Rahul went to his bedroom to sleep after finishing his homework on Algebra. In his dream, he saw 3 equations being written on three different shining boxes (shown in the figure below).

They all represent the same equation.

Solution

The correct option is A True
First equation is,
$1 + 2 = x$
If we subtract 2 from both sides, we get
$1 = x - 2$ which is same as $x - 2 = 1$
In the first equation, if we subtract 1 from both sides, the equation will become
$x - 1 = 2$
So all the 3 equations Rahul saw are exactly same.

The correct option is A TrueFirst equation is, 1+2=x If we subtract 2 from both sides, we get 1=x−2 which is same as x−2=1 In the first equation, if we subtract 1 from both sides, the equation will become x−1=2 So all the 3 equations Rahul saw are exactly same.
