[input]solve( y= 1/(2x) - 6, 2x + 6y= 19 )[/input]
y= 1/(2x) - 6
2x + 6y= 19
2x + 6*(1/(2x) - 6)= 19
2x + 6/(2x) - 36= 19 |+36
2x + 6/(2x) = 19+36
2x + 6/(2x) = 55 | *2x
(2x)^2 + 6 = 110x | -6 , -110x
(2x)^2 - 110x = -6 | +6
4x^2 - 110x + 6 = 0
=>
x=-(1/4*sqrt(3001))+54/4)
x=1/4*sqrt(3001)+55/4
insert into y= 1/(2x) - 6
y=-(1/12*sqrt(3001))-17/12
y=1/12*sqrt(3001)-17/12

[input]x*0.64=56[/input]
64% = factor 64(100
x*(64/100)=56 | /(64/100)
x = 56 * 100/64
x = 87.5
