Question

6a=30 solve the variable
​

Answer 1

6a = 30

a = 30/6

a = 5

5 is the answer

Answer 2

Answer: We think you wrote:

6a-30=3

This deals with linear equations with one unknown.

Step by Step Solution:

Rearrange:

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

                    6*a-30-(3)=0  

Step by step solution :

STEP

1  

:

Pulling out like terms :

1.1     Pull out like factors :

  6a - 33  =   3 • (2a - 11)  

Equation at the end of step

:

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  :    2a-11 = 0  

Add  11  to both sides of the equation :  

                     2a = 11

Divide both sides of the equation by 2:

                    a = 11/2 = 5.500

                  a = 11/2 = 5.500
