2. vocab none

3. Solving equations x + 6 = 10y – 5 = 23

4. Solving two-step equations 3n – 7 = 82x + 1 = 5x/4 + 6 = 9 3n – 7 + 7 = 8 + 72x + 1 – 1 = 5 – 1x/4 + 6 – 6 = 9 - 6 3n = 152x = 4x/4 = 3 3n/3 = 15/32x/2 = 4/2(x/4)*4 = 3*4 n = 5x = 2x = 12

5. Try these 5x + 7 = 126x – 3 = 39y/4 + 8 = 12

6. Negative coefficients 5 – 2x = 7-x – 3 = 8 5 – 5 – 2x = 7 – 5-x – 3 + 3 = 8 + 3 -2x = 2-x = 11 -2x/-2 = 2/-2-x/-1 = 11/-1 x = -1x = -11

7. Try these -a + 6 = 8-9 – y/7 = -12
