Question

X+y=14 x-y-14 how many solutions

Answer 1

Answer:

infinite

Step-by-step explanation:

linear equation of two variables has infinite solutions

Answer 2

$\huge\bigstar\sf\red{Answer:}$

$\sf{x+y=14...(1)}$

$\sf{x-y=14...(2)}$

$\sf{Add \ both \ equations, \ we \ get}$

$\sf{2x=28}$

$\sf{\therefore{x=14}}$

$\sf{Substitute \ x=14 \ in \ eq(1)}$

$\sf{14+y=14}$

$\sf{\therefore{y=0}}$

$\sf{Hence, \ the \ given \ equations \ have}$

$\sf{only \ one \ solution.}$

$\sf{i.e \ (x,y)=(14,0)}$
