First bring like terms together before simplifying
First distribute the 2/3.
(2/3)n + (2/3)*6 = 10
(2/3)n + 4 = 10
Subtract 4 from both sides
(2/3)n = 6
Multiply both sides by (3/2) to clear the fraction
n = 9
Rounded 62 .1
But it goes on for a while but its 62.58...
29
2x29=58-3 =55
3-2x (x=29) =55
29x2=58-3
I do not know I will tell u but I think it is 65?
