This is the hardest 7th can get in Sweden---v
6x + (3x - 5) = 22
Answer: X = 3
log(300 / x) + √(x + 6) - (2)^(4 - x) + [(x + 2) / (x + 1)](4) = 8Source(s): As far as I know, without using Newtonian approximation, there is no way to solve this problem algebraically through separation of variables. Have fun!
However, x = 3, as you can check it yourself.
x^3 + 3x^2 - 5x = 3
idiot who doesn't belong in 7th grade?
