Step-by-step explanation:

It has been given that

$\frac{2^{3x-1}+10}{7}=6$

Cross multiplying, we get

$2^{3x-1}+10=42$

Subtract 10 to both sides

$2^{3x-1}=32$

Write 32 in exponent form

$2^{3x-1}=2^5$

Since, base of both sides of the equation is 2. Hence, the exponent must be equal.

3x-1 = 5

Solve for x

3x = 5+1

3x = 6

x = 2
