Math urgent! :( plz help

3. Which of the following equations has an infinite number of solutions?
3x  3 + 4x
2y+ 4 y = 16
7x + 5 = 4x + 5 + 3x
6y 2 =2 (y1)
Write the inequality and solve for the following problem:
The result of 6 subtracted from a number n is at least 2
n  2>6; n > 8
n6>2; n > 8
n + 6 > 2; n < 4
n + 6> 2; n> 4

7x + 5 = 4x + 5 + 3x yields 0=0 infinite sols
n6>2
add 6 to both sides
n > 8 
Thanks!

You are welcome :)
