Yhu did it c:
Ok, the first thing yhu want to do is distribute the -3 into the parenthesis. Do that and lemme know what yhu get
Nnesha (nnesha):
standard form mean like this
Ax + By = c
OpenStudy (ria23):
Ok, so yhu equation is 7-3(x-y)=5x+2
Distributing the -3 in... Yhu get 7 - 3x + 3y = 5x + 2 correct?
Now can yhu combine the like terms?
OpenStudy (anonymous):
I think I got it.
8x + 3y = 5?
OpenStudy (ria23):
c: exactly.

Thank you(:

Wait one second...
OpenStudy (anonymous):
??
OpenStudy (ria23):
It would be 8x-3y=5
OpenStudy (ria23):
Do yhu understand why?

Nope. I really suck at math.
OpenStudy (ria23):
Lol, yhu did really good, when yhu combine the like terms, yhu get 5+3y=8x, correct?
OpenStudy (anonymous):
Yeah
OpenStudy (anonymous):
Wait, how did 8x end up in the back? When they move the stuff around it confuses me.
OpenStudy (ria23):
Lol, I'll slow it down

\[7-3(x-y)=5x+2\]
then yhu distribute.
\[7-3x+3y=5x+2\]
So yhu got it that far...

Combine yhur like terms.
Do yhu get it so far? Or did I lose yhu?
