5 (x+0.8) = 16
5x + 4 = 16
5x = 16 - 4
5x = 12
x = 12/5
5x + 4 = 16
5x = 16 - 4
5x = 12
x = 12/5
2009-05-07 10:16 pm
5(x + 0.8) = 16
5*x + 5*0.8 = 16
5x + 4 = 16
5x = 16 - 4
x = 12/5 (2.4)
5*x + 5*0.8 = 16
5x + 4 = 16
5x = 16 - 4
x = 12/5 (2.4)

5(x + 0.8) = 16
5x + 4 = 16
5x = 16 - 4
5x = 12
x = 12/5 or 2.4
Done
5x + 4 = 16
5x = 16 - 4
5x = 12
x = 12/5 or 2.4
Done

5 times X = 5x
5 times 0.8 = 4
5x + 4 = 16
5x= 12
x = 2.4
5 times 0.8 = 4
5x + 4 = 16
5x= 12
x = 2.4
2009-05-07 10:05 pm
5x+4=16
5x=12
x=12/5=2.4
5x=12
x=12/5=2.4

divide by 5. x+.8=16/5
subtract 8 x=12/5
subtract 8 x=12/5

First, divide by 5
(x + 0.8) = 3.2
Next, subtract 0.8
x = 4
(x + 0.8) = 3.2
Next, subtract 0.8
x = 4
2009-05-07 10:03 pm
(x+0.8)=16/5=3.2
x+0.8=3.2
x=3.2-0.8
x=2.4
x+0.8=3.2
x=3.2-0.8
x=2.4
