the (x,y)=?
(5,-2)
(5,2)
(-5,-2)
(-5,2)​

Answer 1

Answer:

(5, 2)

Step-by-step explanation:

put the x=5,y=2 then in the equation left side is equal to right side

Answer 2

Answer:

Question

✳️Solve the following simultaneous equation. 5x - 3y = 19; X - 6y = -7.find the (x,y)=?

Solution ⬇️

✍️5x - 3y =19...(1)

✍️x - 6y =-7....(2)x⁵

✍️5x -30y =-35....(3) multiplied equation

2 by 5

✍️(-)5x-(+)3y=(-)19...(1) subtracting eq 1 from 3

_______________

✍️-27y = -54

✍️27y=53..{(-}{-}={+})

$= = > y = \frac{52}{27} = \frac{2}{1} = 2$

✳️Substituting value y = 2 in equation 1

✍️5x-3y=19..(1)

✍️5x-3(2)=19

✍️5x-6=19

✍️5x=19+6

✍️5x=25

$= = > x = \frac{25}{5} = \frac{5}{1} = 5$

✍️(x,y)(5,2)is the solution of the given quadratic equation

Step-by-step explanation:
