Answer:

[tex]7) \frac{x+20}{x}=\frac{46}{30}[/tex]

[tex]30(x+20)=46x[/tex]

[tex]30x+600=46x[/tex]

[tex]46x-30x=600[/tex]

[tex]16x=600[/tex]

[tex]x=75/2[/tex]

[tex]x=37.5[/tex]

---------------------

[tex]8) \frac{10}{3x+1} =\frac{22}{7x-1}[/tex]

[tex]10(7x-1)=22(3x+1)[/tex]

[tex]70x-10=66x+22[/tex]

[tex]70x-66x=22+10[/tex]

[tex]4x=32[/tex]

[tex]x=\frac{32}{4}[/tex]

[tex]x=8[/tex]
