Question

x+(3x+20)+(180-x)+(180-3x-20) find x

Answer 1

Answer:

Step-by-step explanation:

x+3x-20=180  

One solution was found :

                  x = 50

Rearrange:

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

                    x+3*x-20-(180)=0  

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  4x - 200  =   4 • (x - 50)  

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x-50 = 0  

Add  50  to both sides of the equation :  

                     x = 50

One solution was found :

                  x = 50

Answer 2

Step-by-step explanation:

x+3x+20+180-x+180-3x-20

4x+200+180-20-x-3x

4x+360-4x

360
