a does not = b
a(x+b)=bx-c
and my test review says the answer is:
ab+c/ b-a
but I keep getting -ab-c/a-b
so my negative signs are the complete opposite of theirs, and I have no idea why. Am I doing it right? Is there a problem with their answer?
here's my work :
a(x+b)=bx-c
ax+ab=bx-c
ax-bx= -ab-c
x(a-b)= -ab-c
x= -ab-c/ a-b
Can anyone confirm my work or show a flaw in it? Thank you so much!
