Find the value of Q in the following system so that the solution to the system is {(x, y) :x-3y=4}.
X-3y=4
Qx-6y=8

a

step-by-step explanation:

answer: i think it is (1,-2)

50.6

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
