The given expression is
[tex]14x - 7 + 3(2x - 5)[/tex]
And we have to find the equivalent expression.
First we simplify the given expression by distributing 3 on 2x-5. That is
[tex]= 14x-7+6x-15[/tex]
Now we combine the like terms, that is
[tex]= 14x+6x-7-15 = 20x -22[/tex]
And that's the simplified expression. And hence the correct option is C .
