Problem: 6y-8=4y+14
is y=3 ,please elaborate

6y - 8 = 4y + 14
6y - 8 - 4y = 4y + 14 - 4y
2y - 8 = 14
2y - 8 + 8 = 14 + 8
2y = 22
2y/2 = 22/2
y = 11

I don't know where you got y = 3, but
as you can see, it doesn't come from
the equation you posted. That equation
gives y the value of 11.

Check.

First, try your value of 3.

6y - 8 = 4y + 14
6(3) - 8 = 4(3) + 14
18 - 8 = 12 + 14 ???
10 ≠ 26
NOPE, y does NOT equal 3.

Now, try 11.

6y - 8 = 4y + 14
6(11) - 8 = 4(11) + 14
66 - 8 = 44 + 14
58 = 58
Definitely works.

Answer: y = 11, not 3
