|8w+5|=21 <br> please show work
Gre4nikov [31]

Answer:

w=-13/4

w=2

Step-by-step explanation:

|8w+5|=21

Step by step solution :

STEP

1

:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     |8w+5| = 21

STEP

2

:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |8w+5|

For the Negative case we'll use -(8w+5)

For the Positive case we'll use (8w+5)

STEP

3

:

Solve the Negative Case

     -(8w+5) = 21

    Multiply

     -8w-5 = 21

    Rearrange and Add up

     -8w = 26

    Divide both sides by 8

     -w = (13/4)

    Multiply both sides by (-1)

     w = -(13/4)

    Which is the solution for the Negative Case

STEP

4

:

Solve the Positive Case

     (8w+5) = 21

    Rearrange and Add up

     8w = 16

    Divide both sides by 8

     w = 2

    Which is the solution for the Positive Case

STEP

5

:

Wrap up the solution

w=-13/4

w=2

What are the coordinates (x, y) at which the graphs of 2x + 3y = 12 and 2x - y = 4 intersect?
Jobisdone [24]

  The coordinates (x,y) are (3,2), If the graphs of 2x+3y=12 and 2x-y=4 are intersect.

Step-by-step explanation:

The given is,

                                         2x+3y=12.................................(1)

                                           2x-y=4....................................(2)

Step:1

            The values of x and y are obtained by elimination method,

            Substrate the equation (1) and (2),

                                          2x+3y=12

                                             2x-y=4

             ( - )

             Equation becomes,

                      (2x-2x)+(3y+y)=(12-4)

                                       (0)+(4y)=(8)

                                                   4y=8

                                                     y=\frac{8}{4}

                                                     y=2

            From the equation (1),

                                           2x+3y=12

                                        2x+3(2)=12

                                            2x+6=12

                                                  2x=12-6

                                                   x=\frac{6}{2}

                                                   x=3

Step:2

            Check for solution,

                                          2x-y=4....................................(2)

            Substitute the values of x = 3 and y = 2 in above equation,

                                        2(3)-2=4

                                             6-2=4

                                             4=4

           Both sides are equal, so the x = 3 and y = 2 is correct answer

Result:

          The coordinates (x,y) are (3,2), If the graphs of 2x+3y=12 and 2x-y=4 are intersect.
