Answer:

$y = 8 \: \: \: x = - 10$

Step-by-step explanation:

$4( - 6x - 9y = - 12) \\ 3(8x + 9y = - 8) \\ \: \: \: \: \: \: \\ - 24x - 36y = - 48 \\ 24x + 27y = - 24 \\ \\ - 9y = - 72 \\ y = 8 \\ \\ \\ \\ \\ - 6x - 9y= - 12 \\ - 6x - 72 = - 12 \\ - 6x = - 12 + 72 \\ - 6x = 60 \\ x = - 10$

Evaluate the limit as x approaches 1 of the quotient of the square root of the quantity x squared plus 3 minus 2 and the quantit

Since the value of the function is the indeterminate form 0/0, L'Hôpital's rule applies. The ratio of derivatives of numerator and denominator is
.. x/ $\sqrt{x^{2}+3 }$
Evaluated at x=1, this is
.. 1/ $\sqrt{1^{2}+3 }$ = 1/2
