Solution - Linear equations with one unknown

Rearrange:

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

                8*(y+4)-2*(y-1)-(70-3*y)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  ((8 • (y + 4)) -  2 • (y - 1)) -  (70 - 3y)  = 0 

Step  2  :

Equation at the end of step  2  :

  (8 • (y + 4) -  2 • (y - 1)) -  (70 - 3y)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   9y - 36  =   9 • (y - 4) 

Equation at the end of step  4  :

  9 • (y - 4)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    9   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 5.2      Solve  :    y-4 = 0 

 Add  4  to both sides of the equation : 
                      y = 4
