To distribute the minus sign outside the parentheses in the expression:

$-6.3y - \left(-10z - 0.3\right)$

Follow these steps:

1. Distribute the minus sign to each term inside the parentheses: $-(-10z) - (-0.3)$

2. The minus sign changes the sign of each term inside the parentheses: $10z + 0.3$

3. Substitute this result back into the original expression: $-6.3y + 10z + 0.3$

So, the equivalent expression is:

$-6.3y + 10z + 0.3$

Tip: When distributing a minus sign, remember that it changes the sign of every term inside the parentheses.
