Answer:

<h2>x=-27</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • equation
  • PEMDAS
<h3>given:</h3>
  • - 8 =  \frac{x}{3}  + 1
<h3>to solve</h3>
  • x
<h3>let's solve:</h3>

step - 1 : define  \\ - 8 =  \frac{x}{3}  + 1

step - 2 :  \\ rewrite

\frac{x}{3}  + 1=   - 8

step - 3 :  \\ subtract \: 1 \: from \: both \: sides

\frac{x}{3}  + 1 - 1 =  - 8 - 1

\frac{x}{3}  =  - 9

step - 4 :  \\ multiply \:  both \: sides \: by \: 3

\frac{x}{3}  \times 3 =  - 9 \times 3

\huge \therefore    x =  - 27

2x-y=4 and y=-2x+8.<br><br> Can anyone help me solve
Komok [63]

Answer:

The correct answer is x = 3 and y = 2.

Step-by-step explanation:

There are many ways to solve systems of equations like this, but I'm going to use substitution.  This means taking the value of y given by the second equation and plugging it into the first equation.  This is modeled below:

2x - y = 4

2x - (-2x+8) = 4

Now, we can simplify the left side of the equation.

2x + 2x - 8 = 4

4x - 8 = 4

We should add 8 to both sides as the next step.

4x = 12

Now we can divide by 4.

x = 3

To solve for y, we can substitute this value found for x back into either one of our original equations.

y = -2x + 8

y = (-2*3) + 8

y = -6 + 8

y = 2

Therefore, the correct answer is x = 3 and y = 2.

Hope this helps!

What is the solution to the system of equations?
Tatiana [17]
If you would like to know the solution to the system of equations, you can do this using the following steps:

y = –5x + 3
<span>y = 1
</span>_______________
1 =<span> –5x + 3</span> 
5x = 3 - 1
5x = 2    /5
x = 2/5 = 0.4

(x, y) = (0.4, 1)

The correct result would be (0.4, 1<span>).</span>

What is the value of x in the equation 8 + 4 = 2 (x minus 1)?
satela [25.4K]

Answer:

x= 7

Step-by-step explanation:

The equation is 8+4= 2(x-1)

Distribute into the parenthesis.

8+4= 2x-2

Now, add.

12= 2x-2

Add 2 to both sides.

12= 2x-2

+2       +2

Then, divide by 2 to both sides to isolate the variable.

<u>14</u>= <u>2x</u>

2    2

x=7
