Answer:
log9
Step-by-step explanation:
Using the rules of logarithms
logx + logy = log(xy)
logx - logy = log(
)
log
⇔ nlogx
Given
2(log18- log3) + 
log
= 2(log(
) ) + log
= 2log6 + log
= log6² + log
= log36 + log
= log( 36 × )
= log9
5n + 7 = 7(n+1) - 2n
First distribute 7 to all terms inside the parenthesis
7(n) = 7n
7(1) = 7
5n + 7 = 7n - 2n + 7
Simplify. Combine like terms
5n + 7 = 5n + 7
True.
If you want to continue:
Isolate the n, move all variables to one side, and constants to the other
5n (-5n) + 7 (-7) = 5n (-5n) + 7 (-7)
0 = 0
True
hope this helps
You pretty much just flip the second fraction and factor
Answer:
11x=1
Step-by-step explanation:
15x+4=5+3x+1x Bring everything with an x in front of it to the left side
15x-3x-1x+4=5 Simplify the x values
11x+4=5 Bring the 4 to the right side
11x=5-4
11x=1
