you have to bring the "y" to one side. 10y - 6 = 2 + 4y 10y-4y = 2 + 6 6y = 8 y = 8/6 If you substitute 8/6 into y you will find that 8/6 is the answer
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
5y + 4 = 4y + 5 y + 4 = 5 (subtracting 4y from both sides)y = 1 (subtracting 4 from each side)
y = 6
5
4y+y=10 5y=10 y=2
4y + 10 = 22 4y - 10 - 10 4y=12 4y 4y 4y=3

4y > 16 divide by 6 both sides; y > 4 This inequality is true for all y greater than 4 (4 is not a solution).
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
5y + 4 = 4y + 5 y + 4 = 5 (subtracting 4y from both sides)y = 1 (subtracting 4 from each side)
....Well...if you mean 4y + 9 = 17, then the answer is 2.If you mean 4y - 9 = 17, then the answer is 6.5.
y = 6
5
-3
y=4
If y + 3y + 10 = 70, then 4y + 10 = 70, and 4y = 60. We then find that y = 60/4 = 15.
