Answer 1

Answer:

weight of Samuel is 60kg

Step-by-step explanation:

Robert weight is y kg

and Samuel weight is x kg

y-15=X

x+y=135

x=60

and y=75

Answer 2

Step-by-step explanation:

let, the weight of samuel be x

if the weight of robert is 15 kg more than samuel

then, weight of Robert =x+15 kg

their combined weight =135 kg

therefore, x+x+15=135kg

=2x+15=135kg

=2x=135kg - 15kg

=2x=120 kg

=x=120 kg/2 =60 kg

So, the weight of samuel =60kg
