HI [ X-2] + 3 = 2X X-2 = 2X-3 X-2 -2X = -3 -2 -X = -3
THEREFORE -X = -1 THEREFORE X = 1
JUST TO CHECK SUBSTITUTE X [X - 2 ] +3 = 2X 1 - 2 +3 = 2 -1 +3 = 2
THEREFORE 2 = 2
WHEN YOU CARRY NUMBERS FROM ONE SIDE OF THE EQUALS SIGN THEY CHANGE THERE POWERS SO ADD BECOMES MINUS MINUS BECOMES A PLUS
DIVIDE BECOME MULTIPLICATION AND MULTIPLICATION BECOMES DIVIDE
THE EQUATION STARTS WITH PARENTHASIS AROUND THE X-2 SO THE +3 HAS TO BE TAKEN OVER TO THE OTHER SIDE OF THE EQUALS SO THAT IT RELEASES [X-2] FROM THE PARENTHASIS
HOPE THIS HELPS
