Y = 3x - 4 . . . (1)
9x - 3y = 14 . .(2)

Putting (1) into (2) gives
9x - 3(3x - 4) = 14
9x - 9x + 12 = 14
12 = 14

Therefore, there is no solution.

<span>. y = 3x – 4.
</span><span>9x – 3y = 14.
by substituiting value of x in second equation
9x-3(3x-4)=14
9x -9x+12=14
12=14 which is not possible so no solution for this question</span>
