Question

if (2^3x -1 + 10) ÷ 7 = 6 , then find the value of x​

Answer 1

Answer:

See the photo. The answer is x = 2.

Answer 2

Answer:

Step-by-step explanation:

2^(3x-1) +10÷7=6

2^(3x-1)+10=42;(7×6)

2^(3x-1)=42-10

2^(3x-1)=32

2^(3x-1)=2^5

According to the law of indices

M^x=M^y

Then

x=y

So 3x-1=5

3x=5+1

3x=6

Divide both sides by 3

x=2
