Solve the equation y. 6=2(y+2)
atroni [7]

Answer:

y = 1

Step-by-step explanation:

Rearrange:

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

                    6-(2*(y+2))=0

Step by step solution :

Equation at the end of step  1  :

 6 -  2 • (y + 2)  = 0

Pulling out like terms :

3.1     Pull out like factors :

  2 - 2y  =   -2 • (y - 1)

Equation at the end of step  3  :

 -2 • (y - 1)  = 0

Equations which are never true :

4.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    y-1 = 0

Add  1  to both sides of the equation :

                     y = 1

One solution was found :

                  y = 1
