Question

solve the equations

1/x + 3/y = 1
6/x - 12/y = 2

a. X= 5/3,y= 15/2
b.x=4 , y=9
c. x=3 , y=11
d. x= 3/4, y= 7/3​

Answer 1

Step-by-step explanation:

$\frac{1}{ x} + \frac{3}{y} = 1 \\ \\ \frac{6}{x} - \frac{12}{y} = 2 \\ \\ let \: \frac{1}{x} = u \: and \: \frac{1}{y} = v \\ \\ u + 3v = 1 \\ 6u - 12v = 2 \:$
