Solve the following equation:
-%284%2F5%29%287y%2B5%29-%286%2F10%29%28-6y-7%29=2y-148%2F25..........both side multiply by common denominator 50
-50%284%2F5%29%287y%2B5%29-50%286%2F10%29%28-6y-7%29=50%2A2y-50%2A148%2F25
-10%2A4%287y%2B5%29-5%2A6%28-6y-7%29=100y-2%2A148
-40%287y%2B5%29-30%28-6y-7%29=100y-296
-280y-200%2B180y%2B210=100y-296
-100y%2B10=100y-296
296%2B10=100y%2B100y
306=200y
153=100y
y=153%2F100->exact solution
y=1.53->decimal solution

Simplify: [(𝑥^3𝑚)^−2𝑛^2/𝑛^-1𝑥^-4]^-2
it's not quite clear what do you have here
my guess is:

+n%5E2%28n%5E2%2A+x%5E8%29%2F%28x%5E6+%2Am%5E2+%29............since x%5E8%2Fx%5E6=x%5E2%2F1
