1)(y-1)/y=5y-1=5y
y-5y=1
-4y=1
y= -0.25
2) y* (30-14)/12 = 36%
y = 0.36*12 / 16
y = 0.27

(y-1)/y=5
y-1=5*y
y=5y+1
-4y=1
y=-1/4
y* (30-14)/12=36%
y(30-14)=4.32
30y-14y=4.32
16y=4.32
y=0.27

1).(y-1)/y=5
y-1=5y
y-5y=1
-4y=1
y=-1/4or -0.25
2).y* (30-14)/12=36%
30y-14y=12x36%
16y=4.32
y=4.32/16 or 0.27
y-1=5y
y-5y=1
-4y=1
y=-1/4or -0.25
2).y* (30-14)/12=36%
