Question

if 5^x‐1=25 and 6^y+2=216 , find the value of y/x‐x/y​

Answer 1

YOUR ANSWER IS -69/130

5x-1=25

5x=26

x=26/5

6y+2=26

6y=26-2

6y=24

y=4

y/x -x/y

y²-x²/xy

4²-(26/5)²/(4)(26/5)

16-(676/25)/104/5

16-(676/25)/104/5

(400-676/25)/(104/5)

(-276)×5/(25×104)

-138/(5×52)

-69/5×26

-69/130
