Answer:
[tex]188.6n-2[/tex]
Step-by-step explanation:
Use PEMDAS. Simplify multiplication:
[tex]7.9*24n=189.6n\\\\7-n+189.6n-54+45[/tex]
Collect like terms:
[tex](7-54+45)+(-n+189.6n)[/tex]
Simplify first parenthesis:
[tex]7-54=-47\\\\-47+45=-2\\\\-2+(-n+189.6n)[/tex]
Simplify second:
[tex]-1n+189.6n=188.6n\\\\-2+188.6n[/tex]
Reorganize:
[tex]188.6n-2[/tex]
:Done
