sam and joe are house painters.
sam makes $5 an hour less than joe.
on a job that took them both 40 hours to complete, they made $1400.
how much does sam make in one hour?
:
let x = Sam's hourly wage
then
(x+5) = Joe's hourly wage
:
40x + 40(x+5) = 1400
40x + 40x + 200 = 1400
80x = 1400 - 200
80x = 1200
x = 1200/80
x = $15 an hr, is Sam's wage

:
Check by finding how much each earned:
40(15) = 600
40(20) = 800
----------------
total: 1400
