Answer:

25c+5d

Step-by-step explanation:

First, write out the equation as you have been given in the problem:

5(3c-[d-2(c+d)])\\

Next, distribute the -2 to the set of parenthesis containing "c+d" and combine any like terms that you can:

5(3c-[d-2c-2d])\\5(3c-[-2c-d])

Then, distribute the "-"to the "-2c-d" in the brackets and combine and like terms that you can:

5(3c+2c+d)\\5(5c+d)

Finally, distribute the coefficient 5 to the terms inside the parenthesis:

25c+5d

Therefore, 25c+5d is you simplified answer to the problem.

-4(9n + 9) = -12(4n - 6).
WITCHER [35]

Answer:

n = 9

Step-by-step explanation:

Step 1: Write equation

-4(9n + 9) = -12(4n - 6)

Step 2: Solve for <em>n</em>

<u>Distribute:</u> -36n - 36 = -48n + 72

<u>Add 48n to both sides:</u> 12n - 36 = 72

<u>Add 36 to both sides:</u> 12n = 108

<u>Divide both sides by 12:</u> n = 9

Step 3: Check

<em>Plug in n to verify if it's a solution.</em>

-4(9(9) + 9) = -12(4(9) - 6)

-4(81 + 9) = -12(36 - 6)

-4(90) = -12(30)

-360 = -360
