Answer: Karen's weight = 125 pounds
Step-by-step explanation:
Let Karen's weight be x , this means that John's weight is 3x.
Two times John’s weight = 2(3x)
Two times John’s weight plus Karen’s weight is 875 pounds implies;
2(3x) + x = 875
6x + x = 875
7x = 875
divide through by 7
x = 125
Therefore Karen's weight = 125 pounds
John's weight = 3 x 125 = 375 pounds
