Question
Which of the following equations have x=4 and y=2 as a solution?
Answer: Option C
:
C
Putting x=4 and y=2 in each of the given equations, we get the following:
2x+3y=12:
LHS =2×4+3×2=14≠ RHS
4x+y=19:
LHS =4×4+2=18≠ RHS
x+y=6:
LHS =4+2=6= RHS
3x+2y=15:
LHS =3×4+2×2=16≠ RHS
Hence, x=4,y=2 isa solution of the equation x+y=6.
