Question

Solve the following pair of simultaneous equations 3^y+1=1/9 and 5^y/125^x=125

Answer 1

Explanation:

`3^(y)` + 1 = 1/9

3^y = -8/9

5^y/125^x = 125

5^y/5^3x = 125

5^(y-3x) = 5^3

y-3x = 3

Your question is incorrect as 3^x can never be negative.

But, now you know y - 3x = 3, so, use this to get the values when you reconsider the correct question.
