.60y= .20y + 100
-.20y=-.20
.40y= 100
divide .40y by .40 and then divide 100 bye .40
y= 250 im positive

.60y=.20y-20y+100
.60y-.20y=100
.40y=100
.40y x100=100x100
40y=10000
y=250

0.60Y=0.20Y + 100
0.60Y - 0.20Y = 100
0.40Y=100
Y=100/0.40
Y= 250

Solve for "y" > 0.60y = 0.20y + 100
First: combine "like" terms > subtract "0.20y" from both sides...
0.60y - 0.20y = 0.20y - 0.20y + 100
0.40y = 100
Sec: isolate "y" on one side > divide both terms by "0.40" >
0.40y/0.40 = 100/0.40
y = 250

subtract y from both sides
.40y = 100
divide by .40
and you get (100/.4) = y
