Question

If we subtract the ___________ number from both sides of an equation, it still holds.

Answer 1

Let us suppose we have an equation $a=5$

After subtracting $2$ from both sides.

$a-2=5-2$

$a-2=3$

$a=3+2$

$a=5$ gives the same equation.

Hence, If we subtract the same number from both sides of an equation, it still holds
