Answer:
The correct option is C.
Step-by-step explanation:
The given equation is
[tex]3x-\frac{1}{5}-\frac{2}{9}x=\frac{124}{5}[/tex]
If two terms have the same variables having same powers, then they are known as like terms.
In the given equation [tex]3x[/tex] and [tex]-\frac{2}{9}x[/tex] are like terms.
So, when we simplify the given equation by combining like terms. we need to combined [tex]3x[/tex] and [tex]-\frac{2}{9}x[/tex] .
Therefore the correct option is C.
