What is the first thing you should do with this equation? Add 4 to each side Subtract 7 from each side Distribute the 7 to the m and 4 7(m-4)=7 I hope you said DISTRIBUTE! Which of the following is the correct way to distribute the 7? 7m - 28 Add 4 to each side 7m - 4 7 7(m-4)=7 The correct answer is 7m - 28. Your equation shouldnow look like : Since this is now a 2-step equation, it should be simple to solve. What two steps will you take to solveit and in what order? (Look closely at the answers.) Subtract 28 and then divide by 7 Divide by 7 and then add 28 Add 28 and then divide by 7 Add 7 and then divide by 28 7m - 28 = 7 7m - 28 = 7 The correct answer is:Add 28 and then divide by 7. So, what does x equal? The correct answer is:Add 28 and then divide by 7. 7m - 28 = 7 x= What is the first thing you should do with this equation? subtract 10 from both sides. Subtract x from both sides Combine the x's to get 3x. Combine the x's to get 5x. 4x -10 + x = 5 The correct answer was "Combine the x's to get 5x."The new equation looks like this: Subtract 5 and then divide by 10. Subtract 10 and then divide by 5. Add 10 and then divide by 5. Divide by 5 and then add 10. What are the next two steps? 5x - 10 = 5 So, what does x = ? The correct answer was "Add 10 and then divide by 5." 5x - 10 = 5 x= What is the first thing you should do with this equation? 4(x-2) + 2x=16 Combine the x's. Add 2 to both sides Distribute the 4 to the x and -2 Subtract 2x from each side I hope you said DISTRIBUTE! Which of the following is the correct way to distribute the 4? 4(x-2) + 2x=16 4x - 2 x - 8 4x - 8 5x -8 The correct answer is 4x - 8. The equation shouldnow look like this: 4x - 8 + 2x = 16 Combine the x's to get 2x. Subtract 2x from both sides. Combine the x's to get 6x. What is the next step? The correct answer is to combine the x's to get 6x.The equation should now look like this: Add 8 and then divide by 6. Subtract 81 and then divide by 6. Divide by 6 and then add 8. Subtract 16 and then multiply by 6. 6x - 8 = 16 What are the next 2 steps? So, what does x =? x= The correct answer is "Add 8 and then divide by 6." 6x - 8 = 16 |
