HateMath!:
containing 550 liter of water is being filled with water at the rate of 75 liter per minute

550L+x*75L/min = 550+x*75

HateMath!:
75 liter per minute from a full 1600 liter tank

1600L-75L/min = 1600-x*75

HateMath!:
How lon will it be before the two tanks have the same amount of water?

[input]550+x*75 = 1600-x*75[/input]

[input]plot( 550+x*75, 1600-x*75, x=0..10)[/input]

550+x*75 = 1600-x*75 |-1600
550+x*75 -1600 = 1600-x*75-1600
-1050+x*75 = -x*75 | +x*75
-1050+x*75+x*75 = 0 | +1050
2*(x*75) = 1050 | /2
x*75 = 525 | / 75
x = 525 / 75
x = 7

[input](x-3)^4+ 30=0[/input]
no real solutions.

[input](x-3)^4-30= 0[/input]
two real solutions.

(x-3)^4-30= 0
(x-3)^4-30+30= 0+30
(x-3)^4= 30
sqrt4((x-3)^4)= sqrt(30)
(x-3) = sqrt4(30) and (x-3) = -sqrt(30)
x = sqrt4(30)+3 and x = -sqrt(30) + 3
