For this case what you should do is the following system of equations: x: skilled laborers y: unskilled laborers By writing the system we have: x + y = 24 25x + 12y = 405 Solving the system: Step 1: -25x + -25y = -600 25x + 12y = 405 Step 2: -13y = -195 y = 195/13 y = 15 step 3: x = 24-y x = 24-15 x = 9 Answer: skilled laborers = 9 unskilled laborers = 15
