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 (y-1)

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

n-6>2; n > 8

n + 6 > 2; n < 4

n + 6> 2; n> 4

  • Math urgent! :( plz help -

    7x + 5 = 4x + 5 + 3x yields 0=0 infinite sols

    n-6>2
    add 6 to both sides
    n > 8
