Answer 3

To simplify the given expression, let's apply the distributive property (also known as the distributive law or the distributive property of multiplication over addition) and combine like terms:

Given expression: -3(x - 4) - 4 - 7(x - 5) + 18

Let's start by distributing the constants -3 and -7 to their respective terms within parentheses:

-3(x - 4) = -3x + 12 -7(x - 5) = -7x + 35

Now substitute these simplified expressions back into the original expression:

-3x + 12 - 4 - 7x + 35 + 18

Next, combine the constants:

12 - 4 + 35 + 18 = 61

Now combine the x terms:

-3x - 7x = -10x

So, the simplified expression is:

-10x + 61
