What is the value of x? 6(-3-x)-2x=14

Answers

Answer 1
Answer:


Let's solve your equation step-by-step:

It's usually easier to rewrite the equation, so let's do that

6(-3-x)-2x = 14

Step 1: Simplify both sides of the equation.

6(-3-x)-2x = 14

Simplify: (Distribute)

(6)(-3)+(6)(-x)+-2x=14

-18+-6x-2x = 14

(-6x + -2x) + (-18) = 14

(Combine like terms)

-8x+-18 = 14

-8x - 18 = 14

Step 2: Add 18 to both sides

-1x-18+18 = 14+18

-8x = 32

Step 3: Divide both sides by -8

-8x/8 = 32/-8

x = -4

Final answer -

x = -4

You can check your work by replacing your x by -4 so your equation will equal 14. Remember, use PEMDAS or your answer will not come out correctly.

Answer 2
Answer: The equation given in the question has one unknown variable in the form of "x" and only one equation is required to find the value of the unknown variable. So it is absolutely possible to find the exact value of "x".
6(-3 - x) - 2x = 14
-18 - 6x - 2x = 14
-18 - 8x = 14
Multiplying both sides of the equation by -1 we get
8x + 18 = - 14
Dividing both sides by 2 we get
4x + 9 = - 7
4x = - 7 - 9
4x = - 16
x = - 16/4
  = - 4
So the value of "x" comes out to be equal to - 4. I hope the procedure is clear enough for you to understand.

The appetizer can be any one of 6 choices.  For each of those ...
The rice can be any one of 4 choices.

Total number of possible combinations is (12 x 6 x 4) = 288 .
there is 27 meals cause if you have 12 entrees and 6 appetizers you still have 12 so 2*6=12 so 2*12=24 and how many times can 4 go into 12 and that is 3 so 24+3=27

                    the answer is 27

An original piece of artwork is 2.75 feet by 2.25 feet a reprint of the artwork is 22 inches by 18 inches are the pieces similar? if so what is the ratio of their corresponding side lengths?

Answers

Yes, the Repainted Artwork is similar to the Original. The 22*18 inch repaint can be recaclculated into a 1.83*1.5 feet repaint. Both can be multiplied by about 1.5 to equal 2.75*2.25. Therefore, the ratio is 1.5.

Distribute The 4 In Problem Number 2. (4*2.5X)+(4*1.25) = 77
Simplify. 10X+5 = 77. Now, Subtract 5 From Both Sides. 
10X = 77-5
10X = 72.
Now, Divide.
X = 72/10. 
X = 7.2.
