Solve the inequality. –1/4x – 8 &lt; 3/4
Firlakuza [10]

Step-by-step explanation:

<u>Step 1:  Add 8 to both sides</u>

-\frac{1}{4}x - 8 + 8 < \frac{3}{4} + 8

-\frac{1}{4}x < \frac{35}{4}

<u>Step 2:  Multiply both sides by -4</u>

-\frac{1}{4}x * -\frac{4}{1} < \frac{35}{4} * -\frac{4}{1}

x > -35

Answer:  x > -35

What is -5x + 15 = 35 - 10x
dezoksy [38]

Answer:

   x = 4

Step-by-step explanation:

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

                    -5*x+15-(35-10*x)=0

Pull out like factors :

             5x - 20  =   5 • (x - 4)

_________________________________________

Solve :    5   =  0

This equation has no solution.

A a non-zero constant never equals zero.

_________________________________________

Solve  :    x-4 = 0

Add  4  to both sides of the equation :

                     x = 4
