The lines x-y-2=0, x+y-4=0 and x+3 y=6 meet in the common point :
Options
- A(1,2)
- B(2,2)
- C(3,1)
- D(1,1)
Correct answer
C. (3,1)
Step-by-step solution
The equation of lines are x-y-2=0 ...(i) x+y-4=0 ...(ii) and x+3 y=6 ...(iii) On solving Eqs. (i) and (ii), we get x=3, y=1 On putting these value in Eq. (iii) 3+3=6 which is satisfied. Thus the required point is (3,1) .
