Solve for x: -2x - 5 = 4
Nata [24]

Answer:

x=−20

Step-by-step explanation:

Step by Step Solution:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    x/5-(-4)=0

Step by step solution :

STEP

1

:

           x

Simplify   —

           5

Equation at the end of step

1

:

 x    

 — -  -4  = 0

 5    

STEP

2

:

Rewriting the whole as an Equivalent Fraction

2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  5  as the denominator :

         -4     -4 • 5

   -4 =  ——  =  ——————

         1        5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x - (-4 • 5)     x + 20

————————————  =  ——————

     5             5  

Equation at the end of step

2

:

 x + 20

 ——————  = 0

   5  

STEP

3

:

When a fraction equals zero

3.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 x+20

 ———— • 5 = 0 • 5

  5  

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  x+20  = 0

Solving a Single Variable Equation:

3.2      Solve  :    x+20 = 0

Subtract  20  from both sides of the equation :

                     x = -20

One solution was found :

x = -20

Susan makes 10% commission on her sales. She also receives a salary of $25,600. How much must she sell to receive a total income
Sav [38]
Susan would have to sell more than $69000 to make over 32,500 and less than $163000 to make under $41900

To calculate this you take the income she wants to make and subtract her salary

32500 - 25600 = 6900

you then multiply this by 10 to calculate the commission she needs to earn

6900 x 10 = 69000

Repeat this for the other side of the income scale.
