Question

How would you solve this equation when -14-7=-7?

Answer 1

r = -8/5

Explanation:

-7 log4 (-10r) = -14

Divide each side by -7

-7/-7 log4 (-10r) = -14/-7

log4 (-10r) = 2

Raise each side to the base of 4

4^ log4 (-10r) = 4^2

-10r = 16

Divide each side by -10

-10r/-10 = 16/-10

r = -116/10

r = -8/5
