1. Two Step Equations with Decimals SWBAT solve two step algebraic equations containing decimals by applying the appropriate properties of equality

2. Review What do you need to remember about the order of operations when solving 2 step equations? What do you need to remember about the order of operations when solving 2 step equations? –Reverse order of operations – undo operations in the opposite order you would complete them. _n_ - 3 = 6 _n_ - 3 = 6 -2 -2  N = -18 2m + 3 = 1 2m + 3 = 1  M = -1 7m +7 = 49 7m +7 = 49  M = 6

3. Examples 19.5 = 0.5t + 14 19.5 = 0.5t + 14 0.6w + 6 = 23.4 0.6w + 6 = 23.4 16.6 = 0.8x -17 16.6 = 0.8x -17 (n ÷ 6.4) + 4.3 = 26 (n ÷ 6.4) + 4.3 = 26 (y ÷ 0.25) + 12 = 77 (y ÷ 0.25) + 12 = 77 _z_ - 0.65 = -0.15 _z_ - 0.65 = -0.15 3.6 3.6

4. Complete the Try these problems on your paper _28p_ = 8.4 _28p_ = 8.4 2  P = 10.08 12.6g – 4.8 = 33 12.6g – 4.8 = 33  G = 3 9k + 4.5 = 2.7 9k + 4.5 = 2.7  K = -0.2 5.1 – 2.3z = 12 5.1 – 2.3z = 12  Z = -3 _w_ + 7 = 1.4 _w_ + 7 = 1.4 9.2 9.2  W = -51.52 7.8 – 2.4y = 3 7.8 – 2.4y = 3  Y = 2
