Question

if 291x+3y=0 and 4x-113y=0 then x+y=​

Answer 1

Answer:

291x+3y=0 4x-113y=0

4x-113y=0

4x=113y

X=113y/4

put the value of X in first eqn

291(113y/4)+3y=0

32883y/4+3y/1=0

32883y-12y/4=0

32871y/4=0

y=0 therefore X= 0

note that whenever constant term is not there in the equation then the value of X and y will always 0
