Maths work help, what is y
[From: ] [author: ] [Date: 12-01-05] [Hit: ]
when doing algebra whatever you do to one side you must do to the other side.-y is an unknown number which you need to find out.104-6y = 10y +24+ 6y to each side104=16y+24-24 to each side80=16ydivide each side by 165=y-104-24=6y+10y80=6y+10y6*5=3010*5=50Therefore y=5-104-6y=10y+24Takeaway 24 from boths sides128-6y=10yAdd 6y to both sides128=16yDivide 16 from 1288=yY is 8-y? y is a letter.......
57836

Next, ask him to add all the number and he gets 257834
Show him the number which you had written as an answer
to this addition earlier in the folded paper and surprise him.

You want to put the like terms on different sides since you only have 1 unknown variable.
104 - 6y = 10y + 24 (minus 10y from both sides)
104 - 16y = 24 (minus 104 from both sides)
-16y = -80 (multiply by -1)
16y = 80 (divide by 16 to get 'y' by itself)
y = 5

Well y is a letter that is apart of the alphabet but in this case y is an unknown number in which you need to find
104 - 6y = 10y + 24 [add 6y to both sides]
104 = 16y + 24. [subtract 24 from both sides]
80 = 16y. [divide both sides by 16]
5 = y
-
104 - 6y = 10y + 24
combine like terms...add (6y) to both sides, subtract (24) from both sides...
104 - 6y + 6y - 24 = 10y + 24 + 6y - 24
80 = 16y
y = 5
check in the original equation...
too easy !

first subtract 24 from both sides.
80-6y=10y
now add 6y to both sides.
80=16y
divide each side by 16
5=y.
when doing algebra whatever you do to one side you must do to the other side.

y is an unknown number which you need to find out.
104-6y = 10y +24
+ 6y to each side
104=16y+24
-24 to each side
80=16y
divide each side by 16
5=y
-
104-24=6y+10y
80=6y+10y
6*5=30
10*5=50
Therefore y=5
-
104-6y=10y+24
Takeaway 24 from boths sides
128-6y=10y
Add 6y to both sides
128=16y
Divide 16 from 128
8=y
Y is 8
-
y? y is a letter.
-
y=5
