(-5) (-2a+3b)

To simplify the expression \((-5)(-2a + 3b)\), you can use the distributive property:

\[ -5 \cdot (-2a) + -5 \cdot (3b) \]

Calculating each term:

1. \(-5 \cdot -2a = 10a\)
2. \(-5 \cdot 3b = -15b\)

Putting it all together, the simplified expression is:

\[ 10a - 15b \]

So, \((-5)(-2a + 3b) = 10a - 15b\).
