Answer:
a) n = 3
b) n = 4
Step-by-step explanation:
a) Start off by multiplying each side by 15
[tex]\frac{15n}{15}=\frac{3(15)}{15}[/tex]
Then simplify the equation
[tex]n=3[/tex]
b) Start off by canceling the common factor of 5
[tex]\frac{n}{9} =\frac{4}{9}[/tex]
Then simplify the equation
[tex]n=4[/tex]
