Long  Version  from Calculation 1

Equation

1.4x     +     6.1     =      –7.9    


Steps:

Step 1): Multiply Both sides  by   10:

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

Refine:

14x    +    61     =     -79

Step 2): Subtract  61  from both sides:

14x    +    61     -   61       =     -79     -    61

Simplify:

14x          =         140

Divide both sides by  14:

14x/14       =     -140/14

Simplify:

14x/14     =     x   =====>   14x/4

Divide the numbers:

14/14    =    1

=       x

-140/14    =      -10

-140/14

Apply the fraction Rule:

-a/b        =       - a/b

=            -140/14

Divide the numbers:

140/14      =        10

=            -10

Answer,      Letter  Choice, (A),      x        =       -10







Short  Version From Calculator Number 2:

Equation:     1.4x     +    6.1      =      -79

Solution          Option   (A),       x        =     -10

Let's solve your equation step by step:

1.4x     +      6.1       =     -7.9

Step  1     Subtract   6.1    from both sides:

1.4x     +    6.1     -    6.1       =      -7.9       -     6.1

1.4x         =       -14

Step  2  Divide both sides by   1.4:

1.4x/1.4      =          -14/1.4

x                   =          -10

Answer            x        =          -10     Option   (A)







Hope that helps!!!!                                   : )
