Here are the solutions to your homework problems. 1. Many's Goats Step 1: Define the variable. Let x be the number of goats Many sold. Step 2: Write the equation based on the problem. The initial number of goats minus the number sold equals the number left. 23 − x = 9 Step 3: Solve for x. Subtract 9 from 23 to find the number of goats sold. x = 23 − 9; x = 14 Many sold 14 goats. 2. Trees Along the Road Step 1: Define the variable. Let y be the number of trees left. Step 2: Write the equation based on the problem. The initial number of trees minus the number destroyed equals the number left. 30 − 18 = y Step 3: Solve for y. Subtract 18 from 30 to find the number of trees left. y = 12 There were 12 trees left.
