3[-x + (2 x + 1)] = x - 1<br><br><br> what is x
Nataly_w [17]

The answer you are looking for is x=-2.

Solution/Explanation:

Writing out the equation

3[-x+(2x+1)]=x-1

Simplifying inside of the brackets first

Combining like terms, since -x+2x=x

3(x+1)=x-1

*You can remove the parenthesis, if preferred.

Using the Distributive Property on the left side of the equation

3x+3=x-1

Now, subtracting the "x" variable from both sides

3x+3-x=x-x-1

"x-x" cancels out to 0.

3x+3-x=-1

Combining like terms and simplifying

3x-x+3=-1

2x+3=-1

Subtracting 3 from both sides of the equation

2x+3-3=-1-3

"3-3" cancels out to zero.

2x+0=-1-3

2x=-1-3

Simplifying the right side of the equation

2x=-4

Finally, dividing both sides by 2

2x/2=-4/2

Simplifying the final part of the problem

Since 2x/2=x and -4/2=-2

x=-2

So, therefore, the final answer is x=-2.

Hope that this has helped you. Good day to you.

The sum of a number 8 and twice the number X is 28
hichkok12 [17]

<u><em>ANSWERS ARE AT THE BOTTOM</em></u>

<u><em></em></u>

<u><em>To solve this question, we need to write the questions algebraically. Let's look at the problem first: The sum of a number 8, and twice the number x is equal to 28.</em></u>

<u>Algebraic form:</u>

8 + 2x = 28

<u><em>Lets solve this!</em></u>

<u><em></em></u>

8 + 2x = 28            (Algebraic Form)

2x = 28 - 8             (Subtract 8 from both sides)

2x = 20                  (Divide by 2)

<u><em>x = 10</em></u>                     (Answer)

<u><em>ANSWER:</em></u>

<u><em></em></u>

<u><em>x = 10</em></u>

Which of the following is a solution to the differential equation xy′−3y=6 ?
ololo11 [35]

Answer:

y = 5 {x}^{3}  - 2

Step-by-step explanation:

The given differential equation is :

xy′−3y=6

We want to determine which of the following options is a solution to the differential equations.

The function that satisfies the differential equation is a solution.

We can verify that

y = 5 {x}^{3}  - 2

satisfy this differential equation.

We differentiate to get:

y' = 15 {x}^{2}

We substitute the function and its derivative into the differential equation to get:

x(15 {x}^{2}) - 3(5 {x}^{3}   - 2) = 6

We expand and simplify on the left:

15 {x}^{3}- 15 {x}^{3}   + 6= 6

This simplifies to:

6 = 6

Verified.

We can show that all the other functions do not satisfy this differential equation
