Solve each equation.

$\log_5(2x) = 3$
Hint (a):
Use the definition of a logarithm.
Step (a):
$5^3=2x$

$\log_5(x + 1) = -1$
Hint (b):
See part (a).

$\log(4) − \log(x) = 2$
Hint (c):
Use the properties of logarithms.
Step 1(c):
$\log\left(\frac{4}{x}\right)=2$
Step 2(c):
$10^2=\frac{4}{x}$

$2 \log_3(6) + \log_3(y) = 4$
Step (d):
$\log_3(6^2y)=4$
