2(n+5) + 3 = 7n-18
distribute
2*n + 2*5 + 3 = 7n-18
2n + 10 + 3 = 7n - 18
2n + 13 = 7n - 18
-5n = -31
n = 31/5

2%28n%2B5%29%2B3=7n-18 Start with the given equation.


2n%2B10%2B3=7n-18 Distribute.


2n%2B13=7n-18 Combine like terms on the left side.


2n=7n-18-13 Subtract 13 from both sides.


2n-7n=-18-13 Subtract 7n from both sides.


-5n=-18-13 Combine like terms on the left side.


-5n=-31 Combine like terms on the right side.


n=%28-31%29%2F%28-5%29 Divide both sides by -5 to isolate n.


n=31%2F5 Reduce.

Answer:

So the solution is n=31%2F5
