Question 337427
(1)Luke has $5 more then Sam
if sam has $x
luke = x+5
(2)Together they have $73
x+x+5 =73
2x+5=73
add -5 to both sides
2x+5-5=73-5
2x=68
divide by 2
2x/2 = 68/2
x= 34 
Sam has $34
Luke has x+5 
= 34+5=39
how much money does each have?

(1)there were 12 people on the jury
(2)there were 4 more men then women
how many men where there?
let women be x
men = x+4
x+x+4=12
2x+4 =12
2x=8
x=4 women
(1)lee bycycled 3km farther than wing
(2)the sum of the distances they biked was 25km
how far did each bicyclist go?

wing bikes x km
lee bikes x+3 km
x+x+3=25
2x+3 = 25-3
add -3
2x=22
divide by 2
x=11 wing
lee = 14 km
