Question 98009
how to solve
: 
4(2n-1) = (6n+4)+1
:
Multiply what's inside the brackets:
8n - 4  = 6n + 4 + 1
:
8n - 4  = 6n + 5
:
Add 4 to both sides
8n - 4 + 4 = 6n + 5 + 4
:
8n = 6n + 9
:
Subtract 6n from both sides:
8n - 6n  = 6n - 6n + 9
:
2n = 9
:
n = 9/2 or 4.5
:
:
Check solution, substitute 4.5 for n in the original equation:
 4(2(4.5) - 1) = (6(4.5) + 4) + 1
 4(9 - 1) = (27 + 4) + 1
 4(8) = 27 + 5
