Daily Math Problem:

Mr. Brown and his wife have a combined weight of 370 pounds. Mrs. Brown weighs 155 pounds less than twice her husband’s weight. How much does each of them weigh?
 

Solution:

  1. If x stands for Mr. Brown’s weight, then 2x -155 stands for Mrs. Brown’s weight (because she weighs 155 pounds less than twice her husband’s weight).
  2. We can now set up an equation in x:
    1. x + (2x -155) = 370
    2. 3x – 155 = 370
      1. Add 155 on both sides to isolate 3x.
    3. 3x = 525
      1. Divide by 3 on both sides of the equation to find x.
      2. x = 525/3
    4. x = 175 pounds

In conclusion, Mr. Brown weighs 175 pounds
Mrs. Brown weighs 2(175) – 155 = 350-155 = 195 pounds
