Answer:
6^ (-15) = x
Step-by-step explanation:
6^-8 = blank 6^7
6^-8 = x* 6^7
Divide each side by 6^7
6^-8 / 6^7 = x 6^7 / 6^7
6^-8 / 6^7 = x
Since the bases are the same, we can subtract the exponents
6^ ( -8-7) = x
6^ (-15) = x
57 + x + x + 130 = 167
57 + 2x + 130 = 167
187 + 2x = 167
- 187 - 187
---------------------------
2x = -20
------ -------
2 2
x = -10
