  1. This was Damon's answer. Which part don't you understand?

    "well, we know that both are y so
    6x-5 = -x+9
    7 x = 14
    x = 2
    then y = -x+9 = -2+9 = 7 ">""

  2. How did you get 7 & 14?

  3. 6x-5 = -x+9

    Add x to both sides of the equation

    6x + x - 5 = -x + x + 9

    7x - 5 = 9

    Add 5 to both sides of the equation

    7x = 14

  2. Substitution Method-Plz help

    Use the Substitution method to solve the system of equations. x + y = -4 x - y = 2 solve for x in the second equation. x= y+2 Put that in for x in the first equation: x+y=-4 (y+2) + y = -4 solve for y. Then, x= y+2 i don't get

    so would the new eqaution be... 2x+8=10 then.. 2x=2 x=1? We know that y = x + 8. So if x + y = 10, then x + x + 8 = 10. but what about the y?ANd what do I do afetr that? If you know what x equals, then you can calculate what y

    how would you solve for y in this problem: x=(y^2+3y)^(1/3) I got: y= x^3/y - 3 ? and for this problem: x= 1/[(y^2+3y-5)^3] I got: y = y/x + 5/y - 3? However, I do not know how to solve for y explicitly. I don't think quadratic
