Solution - Linear equations with one unknown
a=31/3=10.333
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 : 
                     10-(3*(a-7))=0 
Step by step solution :
Step 1 :
Equation at the end of step 1 :
  10 -  3 • (a - 7)  = 0 
Step 2 :
Equation at the end of step 2 :
  31 - 3a  = 0 
Step 3 :
Solving a Single Variable Equation :
 3.1      Solve  :    -3a+31 = 0 
 Subtract  31  from both sides of the equation : 
                      -3a = -31 
Multiply both sides of the equation by (-1) :  3a = 31 
Divide both sides of the equation by 3:
                     a = 31/3 = 10.333 
One solution was found :
a = 31/3 = 10.333How did we do?
