Question

2020x+2019y=0and 2109x+2020y=0 then the solution is
a. 2019,2020
b. 2020,2019
c. 0,2019
d. 0,0​

Answer 1

Step-by-step explanation:

you can use two methods :-

1) elimination method in which you can eliminate x or y from these equations. Eliminating x will give you the value of y and then putting the value of y in any one of the equation leads to the value of x and vice - versa.

2) substitution method in which substitute the value of x in form of y from one equation and put it to the another equation, you will get the value of y and then putting the value of y you will get the value of x and vice - versa.

try it, if you have any doubt message me, i will give the solution.

Answer 2

Answer:

0,0

Step-by-step explanation:

as 2020x+2019y=0

y= -2020x/2019

putting this value in equation 2nd,

2019x + 2020×(-2020/2019)x = 0

=( -4039/2019) x = 0

= x = 0

putting x=0 in equation 1,

we shall get y=0.

so, x=0

y= 0.
