Answer:

Step-by-step explanation:
Here, the given expression is:

Now, by logarithm rules, we know
if 
, then x =
Comparing here, b = 10 and z = 2
⇒ y = 
or,

and I'm sorry if I'm wrong but its better than the other guys answer <3
Answer:
x = 
Step-by-step explanation:
Given
y =
( multiply both sides by x - 5
y(x - 5) = 4 - 3x ( distribute left side )
xy - 5y = 4 - 3x ( add 3x to both sides )
xy + 3x - 5y = 4 ( add 5y to both sides )
xy + 3x = 4 + 5y ← factor out x from each term on the left side
x(y + 3) = 4 + 5y ← divide both sides by y + 3
x = 
70/10= 7
So,
77/10-70/10= 7/10
You need to subtract 7/10 from 77/10 to make 7.
I hope this helps!
