Answer:
(-3,4)
Explanation:
Quick way to answer such questions.
since it is a points in the form (x,y)
You take a point assume we take (-3,4).
we can see x=-3 and y=4.
Then we substitute it back into the original equation let take y=1-x
from the point y = 4 and x=-3, therefore the equation will
4=1--3 which is 4=4. this satisfied the condition
By Using calculation to answer such questions.
we can equate both expression in the form
8x^2+47x+73=1-x
bring all variables and constant to the left side
8x^2+47x+x+73-1=0
adding like terms
8x^+48x+72=0
dividing through by 8
x^2+6x+9=0
we multiply c by a which are 1 and 9 in the equation then we have to find a number that we multiply it will give us 9 and when added we get 6
so the numbers are 3 and 3. therefore
x^2+3x+3x+9=0
factorize it
x(x+3)+3(x+3)=0
(x+3)(x+3)=0
Therfore x+3=0
which x=-3
after getting x we substitute back into the original equation. So
8(-3)^2+47(-3)+73=4
so the answers are x=-3 and y=4
