  1. since addition is commutative, you can rearrange things to get
    14x^2-12x^2 + 3x+11x +4-3
    now use the distributive property to get
    (14-12)x^2 + (3+11)x + (4-3)
    not so hard now, eh?

    could you walk-through the steps to solving this problem because I am stuck; 3x-5(3x-7)=2(x+9)+45 Let me know if you have a question in any step. 3x-5(3x-7)=2(x+9)+45 3x-15x+35= 2x+18+45 -12x+35 = 2x+63 -35 -35 -12x= 2x +63-35

    explain how to put 7y-14x=21 in slope intercept form. You want y=mx + b 7y-14x=21 add 14x to both sides, divide both sides by 7. thanks you
