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 :

                     70^2*y-(171500)=0 

Step by step solution :

Step  1  :

 1.1     70 = 2•5•7

(70)² = (2•5•7)² = 2² • 5² • 7²

Equation at the end of step  1  :

  ((22•52•72) • y) -  171500  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   4900y - 171500  =   4900 • (y - 35) 

Equation at the end of step  3  :

  4900 • (y - 35)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    4900   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    y-35 = 0 

 Add  35  to both sides of the equation : 
                      y = 35
