Answer 1

x+5+x+13+x=197
3x+18=197

Answer 2

Paul's weight = 72.67 kg

John's weight =64.67 kg

David's weight = 59.67 kg

Step-by-step explanation:

Let the weight of Paul be x

Johns is in 8 kg lighter than Paul.

John's weight = x-8

David's mass is 5kg less than johns

David's weight = x-8-5 = x-13

Their total mass is 197 kg

So, x+x-8+x-13=197

3x-21=197

3x=218

$x=\frac{218}{3}=72.67 kg$

Paul's weight = 72.67 kg

John's weight = x-8 =72.67 -8=64.67

David's weight =  x-13 = 72.67 -13=59.67
