the x is going to be a negative number to get the 3. so start off minus 5 from plus 5 and minus five from the other side too. the positive 5 and the negative cancel out and then take it fromt here with three and the negative 5.
well you would want to find x so you want to be itself first subtract 5 on both sides to get x by itself and whatever you do to one side you have to do to the other X +5=3 -5.-5 x= -2 < that's your answer
