Question
3x+15=10 is a simple equation. If 5 is added to the left-hand side of the equation, the equation remains the same as the given equation.
Answer: Option B
:
B
If 5 is added to the left-hand side of the equation 3x+15=10, we get 3x+15+5=10.
The value on the left-hand side is increased but it remains same on the right-hand side. So, equality doesn't hold good now. 3x+15+5≠10.
Equality sign remains unchanged only when same quantity is added on both sides, i.e., 3x+15+5=10+5.
Thus, the equation does not remain same as the given equation.
