well,
(-4)(-3x) = 12x
5(-7) = -35
To simplify the expression -4(-3x) + 5(-7), we'll apply the distributive property and combine like terms. Here's how you can do it step by step:
Step 1: Distribute the -4 and -3x:
-4 * (-3x) = 12x
So the expression becomes:
12x + 5(-7)
Step 2: Distribute the 5 and -7:
