dding-the-same-number-to-both-sides-of-an-equation-yields-an-equivalent-equation

Question

Using the balance-scale analogy, which statement correctly explains why adding the same number to both sides of an equation yields an equivalent equation?

Accepted Answer

Adding the same amount to both sides keeps the balance unchanged, so the equality remains true

Answer

Adding the same number eliminates constants on both sides automatically

Answer

Adding the same number forces both sides to equal zero

Answer

Adding any numbers to both sides maintains equality as long as subtraction is used later
