Answer:

a. infinite solutions

Step-by-step explanation:

The given equation is [tex]\frac{1}{5}(2x-15)=\frac{1}{10}(4x-30)[/tex]

We multiply through by 10 to get:

[tex]10*\frac{1}{5}(2x-15)=10*\frac{1}{10}(4x-30)[/tex]

[tex]2(2x-15)=4x-30[/tex]

[tex]4x-30=4x-30[/tex]

Add 30 to both sides

[tex]4x-30+30=4x-30+30[/tex]

[tex]4x=4x[/tex]

[tex]x=x[/tex]

There is infinitely many solution
