Question

Solve the equation for x and y:
$3^{x} = 9*3^{y} , 8*2^{y} = 4^{x}$

Answer 1

Answer: 3 power x =9*3 power y            

• 3 power x=3 power z*3 power y

3 power x = 3 power y+ z

x= y+ z

y= -1

8*2 power y =4 power x

• 2 power 3 *2y=(2 power 2)power x

2 power 3+y= 2 power 2x

3+y= 2x

1+2+y=2x

1+x=2x

x=1
