Answer:

x = 3, y= -1

Step-by-step explanation:

12x-y=37

-5x-y=-14

12x-y=37

-1(-5x-y)=-1(-14)

12x-y+5x+y=37+14

17x = 51

(17x)/17 = 51/17

x = 3

12(3)-y=37

36-y=37

-y = 1

y = -1

Solve with completing the square method:<br>6x²-7x+2=0 and  ax²+bx+c=0
Norma-Jean [14]
6x ^2-7x+2=0\\ \\ a=6 , \ b = -7 , \ c=2 \\ \\\Delta = b^{2}-4ac = (-7)^{2}-4*6*2=49-48=1 \\ \\x_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{7-\sqrt{1}}{2*6}=\frac{7-1}{12} =\frac{6}{12}= \frac{1}{ 2}\\ \\x_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{7+\sqrt{1}}{2*6}=\frac{7+1}{12} =\frac{8}{12}= \frac{2}{ 3}
