Theresa Weber · Answer 1

26 = 7 (g-9) + 12

26-12 = 7 (g-9) + 12-12

14=7 (g-9)

14/7 = 7 (g-9) / 7

2 = g-9

2+9 = g-9+9

11 = g

Check:

26 = 7 ((11) - 9) + 12

26 = 7 (2) + 12

26 = 14+12

26 = 26

Dax Zimmerman · Answer 2

Use the distributive property

7g - 63 + 12 = 26

subtract 12 from both sides

7g - 63 = 14

Add 63 to both sides

7g = 77

divide 7 to both sides

77/7 = 11
