<u>Solve the two-step equation and identify the steps.</u>

Equation:  1.4x     +     6.1     =      –7.9    

<u>Solution:   ======>     x        =       -10</u>


<u>Long  Version  from Calculation 1</u>

<u>Equation</u>

1.4x     +     6.1     =      –7.9    


<u>Steps:</u>

<u>Step 1): Multiply Both sides  by   10:</u>

1.4x  *  10     +     6.1   *   10    =      –7.9   *    10

<u>Refine:</u>

14x    +    61     =     -79

<u>Step 2): Subtract  61  from both sides:</u>

14x    +    61     -   61       =     -79     -    61

<u>Simplify:</u>

14x          =         140

<u>Divide both sides by  14:</u>

14x/14       =     -140/14

Simplify:

14x/14     =     x   =====>   14x/4

<u>Divide the numbers:</u>

14/14    =    1

=       x

-140/14    =      -10

-140/14

<u>Apply the fraction Rule:</u>

-a/b        =       - a/b

=            -140/14

<u>Divide the numbers:</u>

140/14      =        10

=            -10

<u>Answer,      Letter  Choice, (A),      x        =       -10</u>







<u>Short  Version</u> <u>From Calculator Number 2:</u>

Equation:     1.4x     +    6.1      =      -79

<u>Solution          Option   (A),       x        =     -10</u>

<u>Let's solve your equation step by step:</u>

1.4x     +      6.1       =     -7.9

<u>Step  1     Subtract   6.1    from both sides:</u>

1.4x     +    6.1     -    6.1       =      -7.9       -     6.1

1.4x         =       -14

<u>Step  2  Divide both sides by   1.4:</u>

1.4x/1.4      =          -14/1.4

x                   =          -10

<u>Answer            x        =          -10     Option   (A)</u>







Hope that helps!!!!                                   : )

Write an equation of the line that passes through (0, 4) and (0, -3)
andreev551 [17]

Answer: Slope is undefined. x=0

slope calculation: -3-4/0-0 = -7/0 and anything divided by 0 is undefined

the x value in the coordinates is 0 so it’s x=0 line.

vertical lines always have undefined slopes
