Easy examples of solving an equation by adding and dividing: You need to eliminate x from one side, and eliminate constants from the x side. 2x = 6, divide both sides by 2, x = 3 is the solution. x+1 = 5, subtract 1 from both sides, x=4 is the solution. 3x-2=4, add 2 to both sides, 3x=6, divide ...
