Question

Find the value of unknown variable in 5x  5= 2x + 7

Answer 1

Answer:

Step-by-step explanation:

Rearrange:

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

                    5*x-5-(2*x+7)=0

STEP  1 :

Pulling out like terms

1.1     Pull out like factors :  3x - 12  =   3 • (x - 4)  

• Equation at the end of step  1 :

STEP  2 :  Equations which are never true    

2.1      Solve :    3   =  0

• This equation has no solution.

• A a non-zero constant never equals zero.

• Solving a Single Variable Equation:

2.2      Solve  :    x-4 = 0  

•  Add  4  to both sides of the equation :  

•                      x = 4

• One solution was found :

• x = 4

• ....................please mark as brainly.............

Answer 2

Answer:

Pulling out like terms

1.1     Pull out like factors :  3x - 12  =   3 • (x - 4)  

Equation at the end of step  1 :

STEP  2 :  Equations which are never true    

2.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    x-4 = 0  

Add  4  to both sides of the equation :  

                    x = 4
