Question

If you add 5 to the LHS of the equation 9x + 8 = 15, the balanced equation will be .

• A. 9x + 8 + 5 = 15 + 5
• B. 9x + 8 - 5 = 15 - 5
• C. 9x + 8 + 5 = 15 - 5
• D. 9x + 8 - 5 = 15 + 5

Answer 1

The correct option is A 9x + 8 + 5 = 15 + 5

Given equation: 9x + 8 = 15
To add: 5 to the LHS.

We know that, for balancing an equation, exactly the same operations with the same numbers should be performed on both the sides of the equation.

So, if we add 5 to the LHS of the equation 9x + 8 = 15, then, we have to add 5 to the RHS of the same equation.

So, the balanced equation will be 9x + 8 + 5 = 15 + 5.
