-11 + 2r = 5r - 6 - 5

Answer:

x = 0

Step-by-step explanation:

First we need to move either 5r or 2r to the other side, in order to isolate the variable.

We'll move 5r, in this case, by subtracting it from 2r. Now we got: -11 - 3x = -6 - 5.

Next we subtract 5 from -6 to get

-11 - 3x = -11.

Now we can add 11 on both sides to get -3x = 0.

Finally divide by -3 to get x = 0.

Hope this helps :)

Answer:

Step-by-step explanation:

-11 + 2r = 5r - 6 - 5                  combine like terms

-11  +2r = 5r -11 .                       pass the 2r to the other side and it will become                                                                                                                      

         ⤻                                   negative  

-11 = 5r -2r -11                          combine like terms

-11= 3r - 11                               pass the -11 to the other side and now it will        

           ⤾                                 become positive

-11 +11 = 3r                               combine like terms

0 = 3r                                       divide both sides by three

0 = r                                         And then you will get your answer  :)

Use the quadratic formula to find the solutions to the equation x^2-3x+1=0
Gnom [1K]

Answer:

x_{1}=\frac{+3+\sqrt{5} }{2}\\\\x_{2}=\frac{+3-\sqrt{5} }{2}

Step-by-step explanation:

Using:

x=\frac{-b+-\sqrt{b^{2}-4*a*c} }{2*a}

we will have two solutions.

x^2-3x+1=0

So, a=1   b=-3  c=1

x_{1}=\frac{+3+\sqrt{-3^{2}-4*1*1} }{2*1}\\\\x_{2}=\frac{+3-\sqrt{-3^{2}-4*1*1} }{2*1}

We have two solutions:

x_{1}=\frac{+3+\sqrt{5} }{2}\\\\x_{2}=\frac{+3-\sqrt{5} }{2}

Solve for x. 3/4 = x/12 <br> I need work shown to
marta [7]

\frac{3}{4} = \frac{x}{12}

To solve for x you have to bring the 12 to the other side

How  do we do this?

Well if you think about it this is technically what the equation shows

\frac{3}{4} = x * \frac{1}{12}

This means to isolate x you can multiply both sides by 12 and that will cancel \frac{1}{12} from the right side

\frac{3}{4} * 12 = x * \frac{1}{12} * 12

\frac{36}{4} = x * 1\\\frac{36}{4}  = x

\frac{36}{4} can be further simplified to...

9

^^^This is the answer

Check:

3/4 = 9/12

3/4 = 3/4

Hope this helped!
