-5 (n-1) = 7 (n+3)
First, distribute the 5 in the first parentheses.
-5n + 5 = 7 (n+3)
Next, distribute the 7 in the second set of parentheses.
-5n + 5 = 7n + 21
Subtract 7n from both sides.
-5n + 5 - 7n = 21
Subtract 5 from both sides.
-5n - 7n = 21 + 5
Collect like terms.
-12n = 16
Divide both sides by - 12

Step-by-step explanation:
The First step is to distribute the 7 in the second part of parentheses.
-5+5-7n=21
-5-7n=21+5
Then collect the terms
-12n=16
Lastly distribute both sides by - 12
And the answer is - 3/4
