Answer:

1). [tex]x=\frac{5}{170}[/tex]

2). [tex]x=\frac{1}{12}[/tex]

Step-by-step explanation:

(1.)  [tex]\frac{5}{10x}-9=8[/tex]

adding 9 on both sides we get

[tex]\frac{5}{10x}=9+8[/tex]

[tex]\frac{5}{10x}=17[/tex]

[tex]5=17 \times 10x[/tex]

[tex]x=\frac{5}{170}[/tex]

(2.)  [tex]\frac{3}{4x}-3=1+\frac{5}{12x}[/tex]

[tex]\frac{3}{4x}-\frac{5}{12x}=1+3[/tex]

[tex]\frac{9-5}{12x}=4[/tex]

[tex]\frac{4}{12x}=4[/tex]

[tex]12x=1[/tex]

[tex]x=\frac{1}{12}[/tex]
