Divide 3.25 by 5 and get .65
(9,3)
If: 4x = 5y Then: x = 5y/4
5y=25x 25x=5y -5y 25x-5y=0
(-5, 2)
If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8
If: 5y = 4735 Then: y = 947
7
5y + 7 = 25y = -5y = -1
y = -6
x = (-5y + 4) / 7
