Answer:

x = 44/19, y = 33/20

Step-by-step explanation:

Multiply the first eq by 18, to get:

90/y - 36/x = 39

so 36/x = 90/y - 39

in this form we can plug it into the second eq:

90/y - 39 - 24/y = 1 =>  

66/y = 40 =>

y = 66/40 = 33/20

Fill that in the first:

100/33 - 2/x = 13/6 =>

200/66 - 143/66 = 2/x =>

57/66 = 2/x =>

57x = 2*66

x = 132/57 = 44/19

Answer:

y = 1.65

x = 2.32

Step-by-step explanation:

[tex]1)\frac{5}{y} - \frac{2}{x} = \frac{13}{6} == -\frac{36}{x} + \frac{90}{y} = \frac{234}{6} \\2)\frac{36}{x} - \frac{24}{y} = 1[/tex]

Adding 1) + 2)

[tex]\frac{66}{y} = \frac{240}{6} \\ y = \frac{33}{20}\\ x = \frac{44}{19}[/tex]
