can you remind me of how to find y

y x=2 add 'x' on both sides
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
right, now put y=2+x in 1st equation
 one year ago

lala2 Group TitleBest ResponseYou've already chosen the best response.1
where in the first equation

y= 2+x 2+x=x^2+5x3 got this ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
no, u just replace 'y' by '2+x'
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
2+x=x^2+5x3 is correct
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
now bring all 'x' terms on one side you'll get a quadratic in x

hartnn Group TitleBest ResponseYou've already chosen the best response.2
yeah, subtracting 2 from both sides will give you x^2+4x5 =0 can u solve this quadratic ?

lala2 Group TitleBest ResponseYou've already chosen the best response.1
hold on let me try
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
sure, take your time :)
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
yes :) so x=1,5
 one year ago

lala2 Group TitleBest ResponseYou've already chosen the best response.1
Because it asks for a solution not solutions
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
no, there are 2 solutions, because this is quadratic system. put, x=1,5 in yx=2 to get two corresponding values of y
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
solution of the linear quadratic system of equations will be of the form, (x1,y1) and (x2,y2) so u have 2 values of x and corresponding 2 values of y
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.2
yes, 1,3 is one solution, correct. what is other ?
