Solve 7x - 3 = 4x + 6

To solve the equation first collect all the unkown terms (letters) on one side and the known terms (numbers) on the other. Remember you must do the same to both sides to keep it balanced. First remove the 4x from the right hand side by subtracting it. Make sure you do the same to the other side. 7x - 4x - 3 = 6 Then remove the -3 from the left hand side by adding it. Do the same to the other side. 7x - 4x = 6 + 3 Simplify both sides 3x = 9 Then to find x you must divide both sides by three. x = 3
