X/3 - 7 = 5
First add 7 to both sides of the equation to get X/3 = 12, then multiply both sides of the equation by 3 to get X = 36 as your solution.
2X + 5 = 15
First subtract 5 from both sides of equation to get 2X = 10, then divide both sides of the equation by 2 to get X = 5 as your solution.
5X + 7 = 42
First subtract 7 from both sides of the equation to get 5X = 35, then divide both sides of the equation by 5 to get X = 7 as your solution
Whatever you do to one side of the equation
You must do to the other side of the equation
