Solve the equations:
(a+5/4a)+11/12=2/3a
4x/3-(2x+3/6)=9/2
I'll assume the usual carelessness with parentheses and spacing, and go with
(a+5/(4a)) + 11/12 = 2/(3a)
Using a common denominator of 12a, that gives
a(12a) + 3*5 + 11/12 (12a) = 2*4
12a^2 + 15 + 11a = 8
12a^2+11a+7 = 0
That has no real solutions. So, if I interpreted you equation wrong, why don't you use some extra parentheses to make it clear just what you meant?
