Answer:

x = 8

Step-by-step explanation:

Given equation is,

[tex]log_5(10x-1)=log_5(9x+7)[/tex]

We know that,

[tex]log_a(b)=log_a(c)\implies b = c[/tex]

[tex]\implies 10x -1 = 9x + 7[/tex]

Subtracting 9x on both sides,

[tex]x - 1 = 7[/tex]

Adding 1 on both sides,

[tex]x = 8[/tex]

Hence, the solution would be x = 8
