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
