Question 377970: Thank you for being available this evening,
I wanted to know about the 'signs' in between algebra problems with brackets. Here is my example problem:
[3(x+2)+2x]-[4(y+2)-3(y-2)]
Will the minus sign between the problems on the left and right side change the answer at all? Or will it make a difference in the outcome?

Question 381129: 1/3s + 7/9 = 4/3s
(-3/1s)+ 1/3s + 7/9= 4/3s -(3/1s)
7/9= 1/3s multiply both sides by 3/1
7/3=s
This is what I got for my answer, but when I check it, the solution doesn't add up. Where am I going wrong?
