Oxana [17]

Answer:

x=

2

3

​

=1.500

Step-by-step explanation:

(((7•(x-2))-3x)+5)-((0-2•(5x-4))+4)  = 0

STEP

2

:

Equation at the end of step 2

 ((7 • (x - 2) -  3x) +  5) -  (12 - 10x)  = 0

STEP

3

:

STEP

4

:

Pulling out like terms

4.1     Pull out like factors :

  14x - 21  =   7 • (2x - 3)

Equation at the end of step

4

:

 7 • (2x - 3)  = 0

STEP

5

:

Equations which are never true

5.1      Solve :    7   =  0

This equation has no solution.

A  non-zero constant never equals zero.

Solving a Single Variable Equation:

5.2      Solve  :    2x-3 = 0

Add  3  to both sides of the equation :

                     2x = 3

Divide both sides of the equation by 2:

                    x = 3/2 = 1.500

One solution was found :

x = 3/2 = 1.500
