1/3x-137.45=252.60 what is the value of x

nikdorinn [45]

The value of x is 1170.15 because first you add 137.45 from both sides of the equation, then your new equation should be 1/3x=390.05. After that you use the keep change flip method to help you divide 390.05 by 1/3 which will be 390.05 times 3 divided by 1 and your final answer should be x=1170.15 or 1170.15
