Hi
x+7=10     |Subtracting 7 from both sides of the equation
  x = 3
x+14=25     |Subtracting 14 from both sides of the equation  
  x = 11
x-2= -4      |Adding 2 to both sides of the equation
  x = -2
3+x= -11     |Subtracting 3 from both sides of the equation
  x = -14
1/3+f=3/4     |Subtracting 1/3 from both sides of the equation
   f = 3/4-1/3 = 9/12 - 4/12 = 5/1
solving always is the result of isolating the variable on one side of the equation
