Question

(x - 1)x(3x + 8) = (3x - 1)x(x + 5)

Answer 1

Answer:

0.333

Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

 ((x - 1) • (3x + 8)) -  (3x - 1) • (x + 5)  = 0

STEP

2

:

Equation at the end of step 2

 (x - 1) • (3x + 8) -  (3x - 1) • (x + 5)  = 0  

STEP

3

:

STEP

4

:

Pulling out like terms

4.1     Pull out like factors :

  -9x - 3  =   -3 • (3x + 1)  

Equation at the end of step

4

:

 -3 • (3x + 1)  = 0  

STEP

5

:

Equations which are never true:

5.1      Solve :    -3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

5.2      Solve  :    3x+1 = 0  

Subtract  1  from both sides of the equation :  

                     3x = -1

Divide both sides of the equation by 3:

                    x = -1/3 = -0.333

One solution was found :

x = -1/3 = -0.333
