Question

in which quadrant the solutio point of x-y=-5 and x+y=1lie​

Answer 1

Answer:

x-y = -5

-y = -5-x

y = x+5 ---- (i)

x+y = 1

y = 1-x ---- (ii)

from (i) and (ii),

x+5 = 1-x

2x + 5 = 1

2x = 1-5 = -4

x = -4/2 = -2

y = x + 5 ---- (i)

y = -2 + 5 = 3

so, the solution point is (-2,3)

therefore, the solution point lie in 2nd quadrant
