Ordered pair is a pair of numbers written in a particular order and enclosed in brackets are known as ordered pairs. Like :- (x,y)(6,5), (5,8) etc
in an equation when we put the value of x and y then it gives the right result .
find :- ordered pair (x.y) that is a solution to the equation. 4x-y=8
4x-y=8
4x-8=y
now let the value of x=1
4(1)-8=y
-4=y
now the orderd pair of this equation is (1,-4)
now, when we put this value in the equation then
4x-(-4)=8
4x+4=8
4x=8-4
4x=4
x=4/4=1
now put both values in the equation:-
4x-y=8
4(1)-(-4)=8
4+4=8
8=8
hence all condition satisfy the equation
ordered pair (1,-4) is the solution of the equation 4x-y=8
