Yang daily wage, c+5.
Chen daily wage, c.

Yang worked C-3.
Chen worked C days.

Account for the wage of Yang and of Chen:
Yang, %28c%2B5%29%28C-3%29
Chen, c%2AC

Review the variable and expression assignments carefully before continuing.

Each of them earned $180.
highlight%28system%28%28c%2B5%29%28C-3%29=180%2Cc%2AC=180%29%29
Solve this system for c and C.

(Slightly different variable assigning might be an improvement in reading and doing the steps.)
