Math 2 questions :/

Which of the following equations has an infinite number of solutions?

3x ¨C 3 = ¨C4x
2y + 4 ¨C y = 16
7x + 5 = 4x + 5 + 3x
6y ¨C 2 = 2(y ¨C 1)

Write the inequality and solve for the following problem:

The result of 6 subtracted from a number n is at least 2.

n ¨C 2 > 6; n > 8
n ¨C 6 ¡Ý 2; n ¡Ý 8
n + 6 ¡Ý 2; n ¡Ü 4
n + 6 ¡Ý 2; n ¡Ý 4

  2. If you mean

    3x-3 = -4x
    2y+4-y = 16
    7x+5 = 4x+5+3x
    6y - 2 = 2(y-1)

    Then the 3rd one is the same on both sides, so it has many solutions. Any value of x will work.

    n-6 >= 2
