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:
- 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).
-
We can now set up an equation in x:
- x + (2x -155) = 370
-
3x – 155 = 370
- Add 155 on both sides to isolate 3x.
-
3x = 525
- Divide by 3 on both sides of the equation to find x.
- x = 525/3
- x = 175 pounds
In conclusion, Mr. Brown weighs 175 pounds
Mrs. Brown weighs 2(175) – 155 = 350-155 = 195 pounds
