1. Lesson 1.7: Equations with Integers Standards: NS 1.2, AF 2.1, AF 4.2 Objective: Solve one-step equations

2. Objective - To solve simple equations involving integers. Addition/SubtractionMultiplication/Division x + 8 = 2 -8 x = -6 y - 13 = -4 +13 y = 9 -3x = 21 -3 x = -7 m = 8 -2 (-2) m = -16

3. Quick Draw for Points! You will have 30-60 seconds to solve each problem. The text is Equations with Integers

4. Solve. 1) 2) 3) 4)

5. Translate each sentence and solve. 1) The difference of x and 3 is the same as -19. 2) The quotient of y and -5 equals 10.

6. Profit Profit is how much extra you make. So, Profit equals how much you made minus how much it cost you to pay for bills. Profit = Income - ExpensesProfit = Income - Expenses

7. Profit Profit = Income - Expenses Palo sells 40 lasers for $5 each. If a case of 40 lasers costs him $75, how much profit was made? Profit = Income - Expenses Profit =40($5)- $75 Profit =$200- $75 Profit =$125

8. Profit ABC Company has annual expenses of $3200. If they are to make a profit of $4800 this year, what income will they need? Profit = Income - Expenses $4800 = x - $3200 + $3200 $8000 = x Income = $8000
