Asked by Torrie

You have a scale. On one side of the scale is a brick. On the other side of the scale is half of a brick and a ¾ lb weight. If the scale is balanced what is the weight of the brick in pounds.
Answered by Reiny
let the weight of the brick be x lbs

x = (1/2)x + 3/4
times 4
4x = 2x + 3
carry on
