Topic: Expressions and Equations Main Idea: Solving Equations with variables on both sides Aim: RECALL NOTES I’m thinking of a number. If you add four to my number, then double the sum, the result is 20. What is my number? Translate the verbal sentence into an equation, solve and check. 5 times a number increased by three is equal to three times that number increased by 7. What is my number? Solve and Check: 3(y + 5) = 2(2y + 1) In general, how do we solve and check equations of any type? c) d 2 7 Recall Notes Drill: Solve and Check 1) 5a + 14 = 7a + 8 2) 4(2b – 1) = 20 3) 3(2x – 4) = 2x + 8 4) Answer the following question. Show work. Summary: If time: Solve and Check 1) 4d – 7 = 2d + 15 2) 8b – 3 = 1 + 10b 3) 2e – 14 = 3e – 5 4) 5f – 17 = 4f + 36 5) 4(d – 7) = 2d + 16 6) 8b + 3 = 1 + 10b 7) 2e – 4 = 3e – 5 8) 5f – 12 = 4f + 4 9) 4(2b – 1) = 4b + 24 10) 21k – 500 = 73k – 32
