Question

3(8z-1)+10-6(5+3z) please show your work!

Answer 1

`\sf \: 6z - 23`

Explanation:

Given expression,

→ 3(8z - 1) + 10 - 6(5 + 3z)

Let's simplify the expression,

→ 3(8z - 1) + 10 - 6(5 + 3z)

→ 24z - 3 + 10 - 30 - 18z

→ (24z - 18z) + (-3 + 10 - 30)

→ (6z) + (-23)

→ 6z - 23

Hence, the answer is 6z - 23.

Answer 2

I think the question here is to clean up this expression and simplify it.

-- Eliminate the first set of parentheses:

3 (8z - 1) = 24z - 3

-- Eliminate the second set of parentheses:

-6 (5 + 3z) = -30 - 18z

-- Now write the whole thing without the parentheses:

24z - 3 + 10 - 30 - 18z

-- Add up all the z's:

24z - 18z = 6z

-- Add up all the plain old numbers:

-3 + 10 - 30 = -23

-- Write the z's and plain old numbers together:

6z - 23

And that's exactly the same thing as the whole ugly mess
that we started out with in the question.
