Answer» (x,y) ===(1,2) yahi answer hai equal. 2x-y=4put (x, y) =(1,-2) L. H. S. = 21-(-2) =2+2 =4 R. H. S. =4 L. H. S.= R. H. S. equal. 2x-y=4put ( x and y) = (1 and -2) L.H.S. =2×1-(-2) =2+2 = 4R.H.S.= 4L.H.S. = R.H.S. hope this will help you 😊😊😊 1st option is the right answer. x=1. y=-221-(-2)=2+2=4so (x,y)=(1,-2) (x, y) =(1,-2) is the solution first option is the right answer some printing mistake in that question correct ans is x=2 and y=0 2x−y=6 2x=6+y (A)(3,0) LHS=2x−y =2(3)−06=6RHS (3,0)is a solution (B)(0.6) LHS=2xy⇒2(0)−6⇒−6=RHS (o,6)is not a solution (C)(2,−2) LHS2(2)−(−2)⇒6⇒RHS (2,−2)is asolution (D)(3,0) LHS:2(3)−(0)=23=RHS (3,0)is not a solution (E)(21,−5) LHS:2(21)−(−5)⇒1+5⇒6=RHS (21,−5)is a solution. correct ans is 1,-2 put the value of x and y in equation 1 st option is the ans 1st questions is right

Answer»

(x,y) ===(1,2)

yahi answer hai

equal. 2x-y=4put (x, y) =(1,-2) L. H. S. = 2*1-(-2) =2+2 =4

R. H. S. =4 L. H. S.= R. H. S.

equal. 2x-y=4put ( x and y) = (1 and -2)

L.H.S. =2×1-(-2) =2+2 = 4R.H.S.= 4L.H.S. = R.H.S.

hope this will help you 😊😊😊

1st option is the right answer.

x=1. y=-22*1-(-2)=2+2=4so (x,y)=(1,-2)

(x, y) =(1,-2) is the solution

first option is the right answer

some printing mistake in that question correct ans is x=2 and y=0

2x−y=6

2x=6+y

(A)(3,0)

LHS=2x−y

=2(3)−06=6RHS

(3,0)is a solution

(B)(0.6)

LHS=2xy⇒2(0)−6⇒−6=RHS

(o,6)is not a solution

(C)(2,−2)

LHS2(2)−(−2)⇒6⇒RHS

(2,−2)is asolution

(D)(3,0)

LHS:2(3)−(0)=23=RHS

(3,0)is not a solution

(E)(21,−5)

LHS:2(21)−(−5)⇒1+5⇒6=RHS

(21,−5)is a solution.

correct ans is 1,-2 put the value of x and y in equation

1 st option is the ans

1st questions is right
