Answer:
x = 2.
Step-by-step explanation:
(Brainliest?)
So log3(2x-1)+log3(x+7)=3 = log3(3^3) So (2x- 1)(x+7) = 27..... 2x^2+13x - 34 =0 (2x+17)(x - 2) = 0 ..so x = 2 or - 17/2. The solution x = - 17/2 is rejected since we cannot have log 3(2*- 17/2 - 1),a negative number. So the answer is x = 2.
0.3(n-5)=0.4-0.2
0.3(n-5) = 0.2
Dividing 0.3 both side
It has to be a single digit between 1 and 10
