%28%28%285%29%28%28X%2B4%29%2F2%29%29%29-6%29%29%29=29
%28%285x%2B20%29%29%2F2-6%29%29=29
%28%28%285x%2B20%29%2F2%29%29-6%2B6%29=29+6
%28%285x%2B20%29%2F2%29%29%29=35
%28%282%2F1%29%285x%2B20%29%2F2%29%29=(2/1)(35)
%285x%2B20%29%29=70
5X+20-20=70-20
5X=50
5X/5=50/5
X=10
.
Check by plugging (x=10) back into the original equation an solving.
