SOLUTION: Perform the indicated operations and simplify. 6 minus 5/x+3 I know that you first find the lowest common denominator which in this case is x+3. I don't know what to do afterwards.

I could not tell if your problem read 6-5/x+3 or 6 - (5/x+3); so I did it both ways.

6-((5)/(x+3))
Multiply -1 by the (5)/((x+3)) inside the parentheses.
6-(5)/(x+3)
Multiply each term by a factor of 1 that will equate all the denominators. In this case, all terms need a denominator of (x+3).
6*(x+3)/(x+3)-(5)/(x+3)
Multiply the expression by a factor of 1 to create the least common denominator (LCD) of (x+3).
(6(x+3))/(x+3)-(5)/(x+3)
The numerators of expressions that have equal denominators can be combined. In this case, ((6(x+3)))/((x+3)) and -(5)/((x+3)) have the same denominator of (x+3), so the numerators can be combined.
((6(x+3))-5)/(x+3)
Simplify the numerator of the expression.
(6x+18-5)/(x+3)
Subtract 5 from 18 to get 13.
(6x+13)/(x+3)

If it was the other:
(6-5)/(x+3)
Subtract 5 from 6 to get 1.
(1)/(x+3) is your answer
