3. Warm Up

5. 3(2x+3)= 7x - 3 + x LIKE THIS ONE!!!!!

6. Clear Step 1: Clear Parentheses- Use distributive property 3(2x+3)= 7x - 3 + x Combine Step 2: Combine all like terms 6x + 9 = 7x - 3 + x Move Step 3: Move all variables to one side of the equation 6x + 9 = 8x -3 Solve Step 4: Solve using inverse operations 12 =2x

7. Follow steps: Check your solution by substituting the value back into the original equation.

8. Follow steps: Check your solution by substituting the value back into the original equation.

9. If variables cancel there is no solution!

11. Solve. 1. 4x + 16 = 2x 2. 8x – 3 = 15 + 5x 3. 2(3x + 11) = 6x + 4 4. x = x – 9 5. An apple has about 30 calories more than an orange. Five oranges have about as many calories as 3 apples. How many calories are in each? x = –8 x = 6 no solution x = 36 An orange has 45 calories. An apple has 75 calories.

12. What are the steps to solving with a variable on both sides? Can a problem have no solution? When?
