Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y) 2.

It is: 3n-21+4n+8 = 7n-13 simplified
4n+3 For n = 1, the expression evaluates to 4+3 = 7 For n = 2, the expression evaluates to 8+3 = 11 For n = 3, the expression evaluates to 12+3 = 15
3n + 14 = 83n = 8 - 14 = -63n/3 = -6/3n = -2The value of n is -2.
Find the difference of it which is 3, so 3n-1
