how do I solve the equation.×-8=4 can you help me with step by steps on this please

Respuesta :

   This is really easy.
x-4=8 
   what it really is asking you is the value of x
   Isolate x
   take 4 to the other side. not -4 but positive 4
   x=12

you have to isolate the variable so you add eight to both sides x - 8 = 4 +8 +8 now add the other side. remember what is done to one side of the equal sign must be done to the other side. x = 4 + 8 x = 12
