Solve this i keep gettin 59 and i think im wrong

solve for N
7(1+5n)+6(1+4n)=13

7(1+5n)+6(1+4n)=13

multiply out

7 + 35n + 6 + 24n =13

combine terms

13 + 59n = 13

59n = 0

n = 0

7(1+5n)+6(1+4n) = 13
7+35n+6+24n=13
59n=0
n=0

Check:
7(1+0)+6(1+0)=7+6=13

Expanding the brackets you get 13+59n=13 so n=0
