Question 8876
Say that her weight is that mysterious W. If she says that her weight is 60 pounds plus 1/2 of her weight, that's 


{{{ W = 60 + 0.5W }}} <-------------- Start here


{{{ W - 0.5W = 60 }}} <---- subtract 0.5W from both sides


{{{ 0.5W = 60 }}} <----- combine like terms


{{{ W = 120 }}} <----- divide both sides by 0.5. She weighs 120 pounds.
