Question

Solve for x. 5^11x=25^(x+9)

Answer 1

Answer:

55? :|

Step-by-step explanation:

x in (-oo:+oo)

(5/11)*x = 25 // - 25

(5/11)*x-25 = 0

5/11*x-25 = 0 // + 25

5/11*x = 25 // : 5/11

x = 25/5/11

x = 55

x = 55

Answer 2

Answer: x= 2

Step-by-step explanation:

5^11x = 25^(x + 9)

5^11x = 5^2(x + 9)

The 5 on the left hand side will cancel the 5 on the right hand side

11x = 2(x + 9)

11x = 2x + 18

collect like term

11x - 2x = 18

9x = 18

Divide bothside by 9

9x/9 = 18/9

x = 2
