Answer:
Let's call the unknown number x Now let's decrease it by 30, that is x-30 Now let's write out "14 decreased by three times the number", that is 14 - 3x The problem says these are the same, that is x - 30 = 14 - 3x We now want to isolate, or solve for, x Move the x to one side of the equation by adding 3x to both sides 3x + x -30 = 14 - 3x + 3x 4x -30 = 14 Now move the 30 to the right hand side by adding 30 to both sides 4x - 30 + 30 = 14 + 30 4x = 44 Now all we have to do to get x is divide both sides by 4 4x/4 = 44/4 x = 11
