@Taylor0402
OpenStudy (taylor0402):
ok so were were we?
OpenStudy (kg1975):
uhm let me find out
OpenStudy (kg1975):
last thing u said math wise is....
if any number has a variable next to it (a letter) then you ALWAYS multiply unless it says to do otherwise
OpenStudy (taylor0402):
yes so if it says in your equation 2x-y then you would do 2times3+3

OpenStudy (taylor0402):
that minus sign is supposed to be a plus
OpenStudy (kg1975):
2*3+3? ohhhhhhhhhhhhhhhh now i get it! a lil bit
OpenStudy (taylor0402):
yayyyyy
OpenStudy (taylor0402):
so what would the bottom equation be
OpenStudy (kg1975):
What is the value of the expression \[\frac{ 4x-y }{ 2y+x }\]
when x = 3 and y = 3?

okie i remember u plugged the numbers in...
\[\frac{ 4*3-3 }{ 2*3+3 }\]
OpenStudy (taylor0402):
good thats correct now do you know what to do?
OpenStudy (kg1975):
P : Parenthesis
E : Exponents
M: Multiply
D: Divide
A: Addition
S : Subtraction
So we multiply first right?
OpenStudy (kg1975):
4*3?
OpenStudy (taylor0402):
ye and

2*3?
OpenStudy (taylor0402):
very good so what does the equation look like now?
OpenStudy (kg1975):
4*3=12
and
2*3=6
\[\frac{ 12-3 }{ 6+3 }\]
OpenStudy (kg1975):
right?
OpenStudy (taylor0402):
perfect now we have 2 more steps so then we solve the 2 equations

ill be right back while u type i have to use the restroom xD
OpenStudy (taylor0402):
so 12-3+9
and 6+3=9
OpenStudy (taylor0402):
and because of that \[9 \over 9\]
the bar in the middle means to divide the two equations and 9 divided by 9 is 1
OpenStudy (kg1975):
im back
OpenStudy (kg1975):
wait why do u divide the fraction?
