Use the distributive property to remove the parentheses.
-4(6x - 8y)=
-4(6x) - 4(-8y) = -24x + 32y
To remove the parentheses using the distributive property, you need to distribute the -4 to both terms inside the parentheses.
The distributive property states that for any real numbers a, b, and c: a(b + c) = ab + ac.
Applying this to the given expression:
-4(6x - 8y) = -4 * 6x + (-4) * (-8y)
Simplifying:
-4(6x - 8y) = -24x + 32y
