opps o^_^o
Can you help me on linear equations i am not getting them
alright so you know all basic stuff like how to graph them slope intercept form point slope form standard ?
Yea that i understand just the 2 variables part
When it has 2 equations and you have to solve them
I am dont typing idk why it says i am
alright lets start a linear equation would be a start line there are 3 forms \(\large\rm {Standard~form:}\) \[\rm Ax+By=0\] where a should be positive integer so if you get -a you have to multiply or divide both sides by negative one
Yea that i know i jsut need the 2x+3x=4 3x+5x=4 That kind of equation
oh okay
well that is pretty easy as you can see there is only one variable `2x+3x=4` so for this one just solve for x remember x=vertical line y= horizontal line for this question you're going to solve for x that would be the vertical line
are you familiar with `combine like terms ` ?
wait so we are just solving for x for each line?
No no that that sorry i mean 3x+5y=6 4x+5y=4 Something like that LOL
yes right bec there is one variable that's the simplest equation
ohh okay
is that one question or two ?? are you learning about perpendicular parallel lines or system of linear equations ?
I know that it looks like this https://gyazo.com/bde3ee5c3354f6f2e8db6662c392c9cc
i don't get iit so you want to know how to solve these \[\rm 3x-y=7\] \[\rm 2x+3y=1\] or the one u posted above
what's the direction ?
I think i can solve that just plug x in for Y above correct?
Wait nvm i gotta for like 15 mins so ill ask later but thaks for help
there are 3 ways to solve these equations system of linear equations 1st) graphing - for this method you can put both equation into the calculator and if you want to do it by hand you need to solve both equation for y 2nd) Substitution: for this one you have to solve one of the equation either for x or y in order to substitute that into the other equation 3rd)elimination - for this method you need to get same coefficient either for x or y but with opposite sign lst one 4th) matrices-this one is easy if you use calculator (this is the easiest one when you are taking test take less time ;)
\[\rm 3x-y=7\] \[\rm 2x+3y=1\] if you want to do substitution then you should solve first equation for y bec as you can see there is no variable at front of y so you can easily isolate that and then yes substitute y for first equation
alright we will continue whenever u get time =))
Sorry, seems like we are stay, ok so where were we?
Graphing i know you put x and y times by Zero and do it for both and you will get 4 points etc but substitution i think i get and elimination i dont
cool lets do the elimination method for same question you will get the same answer |dw:1448250480082:dw| our goal is to eliminate one of the variable either x one or y(depends on the equation)
