Question

How do you do y+3=0? I'm so totally confused please explain it :(

Answer 1

Y+3=0
   -3 -3
the answer is y=-3

Answer 2

Find y by maybe Pulling out like terms :

 1.1     Pull out like factors :

   -y - 3  =   -1 • (y + 3) 

Equation at the end of step  1  :Step  2  :Solving a Single Variable Equation :

 2.1      Solve  :    -y-3 = 0 

 Add  3  to both sides of the equation : 
                      -y = 3 
Multiply both sides of the equation by (-1) :  y = -3 

One solution was found :                   y = -3
