Question

Solve the simultaneous equations : xy=3, y=x-2

Answer 1

plug y = x - 2 in the equation xy = 3

Answer 2

x^2-2=3

Answer 3

hmmmm nah
it would be x(x - 2) = 3
so x^2 - 2x = 3

Answer 4

ohh right

Answer 5

i don't understand where this is leading to

Answer 6

i need to find 2 x's and 2 y's

Answer 7

on solving x^2 - 2x - 3 = 0
u will get two values of "x" plug them in equations and get corresponding "y"

Answer 8

okay ill try plugging x in

Answer 9

i really don't know there's only one value of x

Answer 10

on solving x^2 - 2x - 3 = 0
-_- u will get x = -1 , 3
now plug value of x in any of the two equation and get corresponding "y"

Answer 11

-2-9-2x-3=0

Answer 12

@scarlettthecamel HMMMM ????
on plugging x = -1
y = x - 2
y = -1 -2
y = -3

Answer 13

similarly plug x = 3

Answer 14

i really don't get any of this

Answer 15

see first of all its given y = x - 2
so plugging y in xy = 3
u get
x(x - 2) = 3
solve the equation for "x"
