Question

If (2^3x-1 + 10) / 7=6.Find the value

Answer 1

Answer: x = 2

Step-by-step explanation:

Given ,

{2^(3x-1) +10 } ÷7 = 6

=> { 2^(3x-1) +10 } = 42

=> { ( 2^3x ) ÷ 2 + ( 20 ÷2 )} =42

=> (2^3x +20)÷2 =42

=> (2^3x +20) = 84

=> 2^3x = 64

=> 2^3x = 2^6

=> 3x=6 { Exponents are equal when equal bases with certain exponents are equal. }

=> x=2

Answer 2

Answer:

Here's the answer of your question ,grab it

Step-by-step explanation:

$( {2}^{3} x - 1 + 10) \div 7 = 6$

$(8x + 9) \div 7 = 6$

$42 = 8x + 9$

$33 = 8x$

$x = 33 \div 8 = 4.125$
