solve this ststem of equations by using the elimination method: 13x-3y=-50 12x+5y=16
please show work
how do we start elinating stuff?
*eliminating stuff, that is
if i have $5 and want to get rid of it, what should I do?
give it to me?
exactly, I should perform an operation whereby I get rid of it :)
we are adding 2 equations, and we want to add them up so that we get rid of one of the variables so that we aint got to mess with it
please just answer the question, u are getting me confused
this is the answering part ....
listen elimination i can do pretty easily bt the question will go into decimal and hard to solve so betta do by substitution
I like elimination more; less steps
this is the means whereby we encourage you to study up on how the process is performed in order that you may gain a better understanding of the principles involved.
i know how to do substitution, but i want to learn how to do it in elimination
i like cramer myself, it is the culmination of elimination and soo much easier
would you agree that we can multiply or divide an equation and not change its inherent properties?
?
ok multiply the second second eq with .8
then y of both equation will b equal hence they will cancel out
@amistre64 Evenly to both sides, yes. :)
wasiqss, the equations don't necessarily have to be multiplied by decimals
of course ;)
it wud get much higher num then, so easiest is multiply by .8
the foundation to elimination is knowing that scaling an equation doenst change it properties: 3x=9 is the same as 5(3x=9): or simply 15x=45
9.6x+3y=1.28 13x-3y=-50
65x - 15y = -250 36x + 15y = 48 101x = -202 x = -2 y = 8
gud one money bird
thankyou moneybird
I personally hate the elimination method. Setting the equations equal to each other by writing both in terms of y is better.
