Question 20874: I dont understand how to solve equations like this 3/5x-7=17 when it comes to fractions I get all confused I understand problems as in 7x-5+9=21 I solve it the following 7x-5x becomes 2x so you then have 2x+9=21 then I would subtract 9 from both sides of the = sign giving me 2x+9-9=21-9 giving me 2x=12 the take 2x/2=12/2 which equals x=6 because 2*6=12 which makes x=6 but when it comes to the fraction in the problem I get all confussed as in this problem 3/5x-7=17 I dont know what to do with the fraction so if you could explain this to me I would really appreciate it very much thanks for your help we are on a block schedule so I dont have this class until Wednesday Nov 30th so I am tring o get this finished by Wednesday Thanks Again Nick

Question 21002: My son is in pre-algebra. I am trying to help him, but I don't know what this is called! I did the questions in excel and came out with the right answers, but I don't know how to get there! I am exacerbated! Anyway...I know I am missing something, but what? -3s+2(-5s+1) s=-3
Ok, you solve what is in the ( ) first (right?); so (-5s+1) is (-5*-3+1)=-5*-3=15 then 15+1=16; so -3s+2(16); then -3*-3=9; 9+2(16), 11(16), 11*16=the wrong answer! How do you get 41? Please help. It has been over 20 years since I did any of this, and I don't remember any of it!
Thank you,
Shelli
