2^x + 3^y = 9
2^x+1 - 3^y+1=8
find x and y​

Suppose :

2^x = t ..**&**.. 3^y = u

t + u = 9 × 3 3t + 3u = 27

》

2t - 3u = 8 2t - 3u = 8

+

5t = 35

5 × t = 5 × 7

t = 7

&

u = 2

Thus :

2^x = 7 ===》 x = Log _ 2 { 7 }

3^y = 2 ===》 y = Log _ 3 { 2 }

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
